back to article El Reg to unleash rocket-powered spaceplane

The El Reg Special Projects Bureau (SPB) is pleased to announce we've finally come up with what we reckon is a worthy successor to our Paper Aircraft Released Into Space (PARIS) project. After a good deal of mulling as to how we could use our PARIS experience to launch an even more improbable and audacious plan to keep the UK …

    Hydrogen's cheaper - have you considered using that in the balloon?

    1. Loyal Commenter

      Whilst Hydrogen is Cheaper

      It has a nasty tendency to diffuse through most things, so that might make the other materials more costly. I also wonder if the legal situation with launching a highly flammable hydrogen balloon differs with that of launching an inert helium one? Anyone know more on this?

        Would be fine with most modern balloons, especially anything made of mylar or similar synthetics.

        The real risk is handling large volumes of the stuff. Unsurprisingly it's not easy to buy canisters of hydrogen without a licence. But, that said, we all know how to make it...

                Hydrogen really not a problem, outdoors

                In the open air you can't get an explosive hydrogen/air accumulation. Hydrogen on its own has no explosive properties. If someone gets really careless and manages to ignite the balloon, it'll burn strongly upwards (away from them).

                It's not well-known that the majority of the passengers in the Hindenburg disaster survived. Of those who didn't, many died of wounds caused by jumping from too great a height, or by heavy metal components of the airship falling onto them. And that was one helluva large balloon.

                The fatal flaw of the Hindenburg, was using an inflammable material for its outer skin. You wouldn't do anything that silly, would you?

        Hydrogen forms H2 molecules, which are much larger than He atoms. This should mean that the diffusion problem is less for hydrogen than for helium.

    Is a model plane with an auto pilot called a "cruise missile" in some circles?

    I thought (probably wrong) that you need a license to develop cruise missiles.

    1. M Gale


      So long as you stick within model aircraft limits (3m wingspan, 7.5Kg weight), no license is required for a UAV. For larger airframes, a specialised license can be obtained. I'm going to hazard a guess and say Lester probably knows all this, or knows a suitable "pilot" (quotes due to it being, err, a UAV).

      Of course the rules in Spain may be different to the rules in the UK. Go have a look at the BMFA's website for the latest Handbook and other resources.

      1. Mips

        Re: Nope

        I thought that limit only applied to conventional propulsion and that you still need a licence for a proper rocket motor.

        1. M Gale

          Dunno about that.

          What I do know is BMFA liability insurance (which is highly limited and only applies on approved land, etc, etc, consult their site for more info) does cover you for up to class M rocket engines, which is pretty fecking huge. We're not talking "firework on a stick". More like "amateur suborbital missile."

          I'm gonna guess that Lester has probably done research in this department though, and might even have larger rocket classes planned.

          At least, I'm sure we're all hoping he has. Teehee.

          >> PARIS was interesting, but it didn't 'fly'..

          > Err, what did it do then? Plummet very, very gently?

          Essentially, yes.

          It _may_ have managed to glide, although with no evidence of it even being gently hand launched into long grass before the big flight, it's hard to see how it could have been anywhere near trimmed for that.

          Not that there was any allowance made for trimming it either.

          Very pleased that this one looks like it might be more of a plane and less of a 'lightweight plane shaped object dropped from a height'.

          +1 to Ardupilot, there are enough other challenges to overcome to get this one to work.

          Probably need tweaking to avoid an Ariane 5 style 'outside the design parameters' disaster though.

          1. Stoneshop Silver badge

            Sheep do not so much fly as...plummet.

            Well, it looks like you wouldn't call what a folded paper aeroplane does when thrown off the n-th floor balcony 'flying' either.

            PARIS managed to end its flight with a surprising lack of damage, from which I dare to draw the conclusion that the craft went relatively slow, which again means a near-horizontal attitude.

            OK, it wasn't guided in any way, but in common parlance the craft, seeing that it did no plummeting to speak of and managing airborne time and distance travelled consistent with the aforementioned lack of plummeting, was flying.

    Good luck with that

    You'll need it. And a lot of permits to fly it too. Autonomous aircraft need an (expensive) permit I believe, although not sure about Spain, but I expect so. Even small ones. The flight control software needs to be completely foolproof and tested to the nth degree (imagine it going wrong and crashing on someone - you'll need insurance).

    Anyway notwithstanding that, flight control software is pretty difficult, as is rocket ignition in flight.

    Still, like I said, good luck!

  34. M Gale

    That concept pic looks awesome.

    ...and you could probably achieve it with fibreglass sheets and resin. Pretty cheap stuff, usually used for making/fixing model helicopter bodies. Could make for an awesome monocoque airframe, leaving plenty of room inside for rocket engines. Will you be just buying off-the-shelf Estes stuff, or making your own engines? Also are you considering solid, liquid or hybrid rocket engines? From what I recall, the Top Gear shuttle attempt used latex and nitrous oxide. Could be worth contacting Rocket Men Ltd to see if they'd like to join forces or find out how much it'd cost to hire their expertise.

    As you're going above GPS heights, I'm going to guess you'll need to work without it, at least at the start of the launch. Solid state barometers can be fettled to work as altimeters, and you already know about solid state gyroes and accelerometers. Problem is, gyroes will tend to drift so you will need to find a way of detecting absolute orientation every now and then (as opposed to the gyroes just telling you how much you rotated since the last measurement). You could go for optical horizon detection (probably a good option as you'll be way above cloud level and presumably launching in the day, even if it would be computationally expensive to analyze a couple of webcam feeds). Another more iffy method is magnetic detection. Apparently the difference in the Earth's magnetic field is measurable over a pretty short altitude difference, so sensors in the wingtips could detect whether you're flying level or not (at the expense of not knowing if you're upside down or not).

    Another (better) method of horizon detection is putting IR sensors in the wingtips and looking for a warmer earth versus a cooler sky. This is used in auto-land mechanisms that are already available, however they have their own drawbacks. You'd need extra sensors above/below to detect inversion, and the behaviour of an autoland system might get a little odd if it approaches a tree line or hilly terrain. I've seen some reports saying the aircraft will automatically bank away from the tree line, but a sharp bank at low altitude will likely end up with a nosedive into the floor.

    Have you thought about possibly taking manual control of the aircraft once it gets low enough, presuming you can find the thing in the sky? Can we have a re-attempt at trying to track the craft via telescope? Also, please put a forward-facing camera on the aircraft this time. PARIS was awesome in very many ways, but it was a shame to not be able to see the ride down from the Playmonaut's perspective.

    Also, perhaps it's possible to have the engines as external modules that get jettisoned after exhaustion? Extra brownie points for having them come down via parachute, shuttle-SRB-style. Extra extra brownie points for sticking cameras on them too.

    For location, maybe you could use a lightweight, hacked smartphone with GPS in addition to the radio beacons? It's likely the batteries would freeze at very high altitude, but so long as it wakes back up properly once things warm up a little (and presuming it comes down in an area with some signal) you'd have a very precise way of recovering your spaceplane (and perhaps SRBs).

    Maybe put a radio beacon on the floor somewhere and see if the plane can home in on it?

    My word, this post is getting long. Hopefully not too long. Dammit Lester, there's just so much stuff to think about here. I'm envious you're getting to do it at all though!

    1. Wommit

      Just an idea

      Use laser ring gyros. No drift and very, very accurate. Light weight too.

      1. M Gale

        Laser ring gyroes


        Problem is, whatever signal you're getting from the gyro has to be converted to digital at some point so the onboard computer can deal with it. Digitisation means quantisation, which means quantisation error, which means drift. Unfortunately we don't have infinite-bit ADCs just yet, nor computers that can deal with infinite accuracy. That and a piezo gyro from a model shop is probably vastly cheaper.

        Still, there are no silly ideas when compared to the overall goal of flinging a model aircraft into space. Let's keep going and give Lester some inspiration!

          Ring Laser Gyros

          I don't think digitisation is that much of a problem, Ring Laser Gyros are used by all the modern airliners to drive their nav systems and autopilots. I think the cost of buying them might be more of a limit, they ain't cheap!!

    2. Andus McCoatover

      far too long ;-)

      If El Reg. can't afford jetex motors*, I'm sure there's a cheap Chinese alternative. However, considering that, wouldn't a few shotgun cartridges give enough thrust? After all, it's not being launched from a "Grassy Knoll" (Downvotes from yanks expected and deserved)


      1. M Gale

        Jetex motors

        Amusing, cheap, but I don't know if they provide enough thrust to lift things vertically. Everything I've seen them on seems to use them to propel the craft horizontally while the wings provide lift in a more normal fashion.

    3. SkippyBing

      Why Horizon Detection

      As long as you design the aircraft to be positivly stable it should self right on release, basically having the centre of gravity below the centre of lift solves the problem.

      After that it's a question of having it head in the right general direction, obvioulsy GPS would be ideal and I believe it's possible to get around the height limit that's mostly an artificial imposition anyway. One of those camera attached to met ballon groups did it a while back. if not just have it follow an appropriate compass direction until it gets below the height limit and then revert to GPS guidance.

      With a dynamically stable platform guidance shouldn't be that much of an issue as once you remove the steer command it should steady up on the new heading.

      I think you could achieve all the above with a smart phone - GPS, compass, guidance control software and link it to the control system via USB. The main thing you'd need this time is some sort of heater to stop the batteries freezing!

      1. M Gale

        Re: Why Horizon Detection

        Well it's not so much horizon detection as attitude detection, and horizon detection is possibly the only way of doing it that's within reach of Garden Shed Engineering.

        As for why, well the idea according to the article is to fly the thing back to base under autonomous control. As well as you build any airframe, all it takes is a gust of wind to completely fuck your orientation up. Under any realistic conditions, simply relying on dihedral wings and rudder control is not going to work very well at all. While there are free-flight gliders that can circle around, they aren't really guided and may well end up anywhere. They also tend to be flown in conditions that are relatively calm compared to whatever might be blowing about up at 30, 40 or 50,000 feet. So long as you can detect attitude, you can keep the wings at a sensible level and therefore not have to worry about suddenly being flipped upside down - or at least, quickly correct things if you do get flipped. Plus at the speed a rocket engine is likely to take you, anything other than sharply swept or delta wings are likely to get ripped straight off. I really want to see that F19 airframe in fibreglass!

        Using a hacked smartphone (or multiple if Lester goes for detachable engines) for everything is a plan though. Cheapy droidphones are under a hundred quid and have more than enough computational grunt for the task. Plus GPS, plus a 3G chipset, unless there are smaller, lighter System On Board platforms that have 3G to talk to home with.

        Mind you, what would it take for a long-ish range nav beacon to send gpsd-compatible messages over rtty? Much better than trying to triangulate a simple ping, and no need to rely on mobile phone coverage.

    4. Martin Gregorie

      This is well below GPS limits

      "As you're going above GPS heights, I'm going to guess you'll need to work without it, at least at the start of the launch."

      Rubbish. GPS works in the ISS orbit. COTS systems have imposed limits of 60,000 ft and 999 kts, to stop evil people from using an off the shelf system to guide a home-brew ICBM, but that's not a technologoical limit and apparently Garmin kit doesn't have the altitude limit implemented.

      At least one person has used a GPS-based auto-pilot to return a met. balloon-launched glider back to base. This reached 74,000 ft and, once the auto-pilot sorted out the trim, was able to head on back home - until it rammed the top of a mountain that happened to be in the way .


      Lester, if you don't know this site, its well worth a look. Its well written and has a lot of information about the temperatures and speeds met in flight as well as good analyses of what went wrong, why, and how the problems were fixed.

      1. M Gale

        I think I should have clarified.

        "Civilian GPS".

        Still, if the module aboard Vulture 1 performed okay, maybe it can be re-used. The thing I'm scared about is that some forums are saying the height+speed limits are imposed on a lot of modules as an "OR" operation, so height exceeded OR speed exceeded. Some are imposed as an AND operation, so height AND speed exceeded. If the Vulture 1's GPS module is an AND, then it'll be fine for measuring a slowly floating balloon's height all the way up to space. However if this rocket plane goes above 999kts, then you could end up with GPS cutting out just when it's needed most: to measure peak height. 1150mph might sound like a big ask, but not out of the range of even a modestly powerful rocket engine in the upper atmosphere with nothing substantially heavy attached to it.

        Though as this is El Reg, and not some bunch of random schmucks, maybe they could be trusted with mil-spec kit?

        1. SkippyBing

          Attitude detection

          Should be possible using one of the sensors in a smartphone as long as it's securely fixed to the airframe. I don't think speed is necessarily an issue either, it only has to go up fast, coming back down could be done at a more leisurely pace, or using one of the more stable lifting body concepts from the X-Series of aircraft to reduce the control issues.

          Going up could be tricky but if you can work out the optimum angle of attack it shouldn't be that hard, although some sort of air density sensor would be useful*. This assumes you want the lift from the wings for going up rather than relying on pure thrust.

          *You could just use a temperature sensor and work the rest out mathematically, you just need an estimation of the Indicated Air Speed that's accurate enough for your control inputs not to cause you to depart controlled flight.

          1. M Gale

            Sensors in a smartphone.

            These tend to be accelerometers, which would be as useless as trying to fly a plane at night in clouds by looking out of the window. Unfortunately the acceleration caused by getting kicked up the backside by a rocket engine will severely skew a smartphone's idea of where "down" is. This is where using a solid state gyro (three of them, they cost about £30-£50 each from an RC supplies shop) would come in handy, alongside horizon detection. The ready-for-RC gyro blocks are quite lightweight, or you can buy the raw components themselves from CPC or Maplin or whoever for even more weight savings. Hell, I have a Blade mCX micro-copter here with a 7 inch rotor span, that has a single-axis tail gyro welded onto the logic board. They are tiny, on the order of Microchip-sized.

            See the reason you need additional horizon-detection measures (be they optical, IR or whatever), is that gyroes don't give you an absolute attitude reading and accelerometers are useless for this purpose when you're undergoing acceleration (or even just wobbling about a bit). Gyroes will tell you how much you've rotated by, but they don't know where "down" is. By using horizon detection, you get an absolute measure of where up and down is that can be taken, say every second or so, whereas the gyroes respond much faster and can be used to interpolate by saying "well up and down was THIS way 0.02 seconds ago and the gyroes say I've rotated THAT many degrees, so up and down must be THERE." Accelerometers can be used for their intended purpose of logging the fact that "holy crap, I'm pulling 10g on this rocket burn, woo fucking hoo!"

            Now you could use solid state barometers to measure both airspeed AND altitude. Airspeed barometer would be attached to a pitot tube, the altimeter one inside the airframe out of any significant draughts. Of course they'd both need calibrating, but the mathematical formula for turning millibars into feet above sea level is pretty well documented. If nothing else it would be a backup or redundant telemetry system in case the GPS module does decide that Lester is trying to bomb the White House and craps out until it descends by a few thousand feet/slows down a touch. Yeah, apparently if the GPS does crap out there may be a bit of hysterisis - it won't just flick back on the minute you go below 60,000ft/1150mph, and there may be a considerable delay.

            This is turning into another long post isn't it?

              Didn't relise gyros were that cheap!

              It's been a while since I had anything to do them beyond using the results.

              As you allude you can use gyros and accelerometers to get an absolute attitude reading as long as you integrate the results a couple of times (INS systems do this in aircraft/submarines etc.), i.e. I was here, I've been pulling 10g in this direction for 5 seconds so I must be there now. Similarly with gyros, I've rotated this way at 3 degrees a second for 2 seconds so I must be 6 degrees right wing low etc. Theoretically as long as they know where down is when you start everything's good but you'd have to run some tests to see if the fidelity is good enough.

              Now what I don't know is if that's more of an overhead than just using the camera on a smartphone* to recognise the horizon is squint, the one issue I can see is that you'll need at least two cameras, one for pitch and one for bank and if the horizon is out of the field of view some way of coping, possibly more cameras.

              Solid state barometers are also a good idea for IAS and Altitude I'm guessing they too cost much less than I thought, of course if you get the OAT as well you can figure out the Mach number...

              *I'm going to keep suggesting smartphones as I'm taken with the idea for some reason. Wonder if I can get one to fly my RC helicopter...

                Just as a thought

                What about the Kinect for horizon detection? It has some impressive sensors/cameras in there, and can be hooked up to anything that can use USB. Get someone to figure out some drivers to run Kinect on a mobile and you've got quite a potent package...

          Further comment

          A little more info: gives the civilian limitations as 60,000 ft AND less than 1000kts

          However, I've seen unattributed statements that many civilian units use an OR relationship instead: and, as I said before, at least some Garmin units are said to limit speed reporting but not altitude.

          Military/space-rated GPS works on the ISS (and Shuttle?). It will apparently work at up to 3000km altitude - which makes sense since the GPS constellation orbits at 20,200 km, so the angular change from ground level to 3000km isn't very significant.

    I'd have a look at DIY Drones for the basis of the autopilot. Most of the groundwork has been laid with their APM; they have good hardware and a well developed IMU.

    ...why a single balloon? Why not a cluster of them? Means you can inflate each balloon less, and therefore reach higher altitudes before they go pop.

    1. Dodgy Geezer Silver badge


      when one balloon goes, so do all the others touching it....

      1. M Gale


        However a single balloon would have to be inflated quite a way to lift all the gear, and would therefore pop at a lower altitude. Multiple balloons would be inflated much less so, and could go higher before going boom.

        That and the cluster could be arranged so no balloons are touching. Think balloon-----string----balloon----string---etc. Or triple cluster of balloons----string----another cluster----etc. The triple cluster would mean the string can go up the middle of the three and not rub against taught latex. Any failures mean only a single cluster goes ka-pop.

        Of course, you could have sensors that measure internal vs external pressure and vent gas accordingly, but that's a whole new complex kettle of fish on top of the existing rather complex autonomous rocketcraft.

        1. Stoneshop Silver badge

          @M Gale

          >Think balloon-----string----balloon----string---etc.

          That, and you'd want to arrange it so that the most-inflated (and thus earliest to pop) balloon triplet is on the bottom, so that there's no knot plus balloon remains falling on the lower balloons, possibly causing a chain reaction.

          You do want to make sure that the release mechanism is not triggered by the jerks of the successive clusters popping, but only by the total loss of lift after the final balloon gives up.

          As for venting, simplest would of course be an overpressure valve rated at, say, 75% of the balloon bursting pressure, but there's always the risk of stuff icing up.

    A plea for a little celebration of science.

    I rather wish I had thought of this for PARIS. But the possibility remains.

    How about including a little science payload? In this case, a stack of photographic film to detect cosmic ray shower particles? Within the allowable payload, this might mean only limited amount is possible, but the possibilities of reproducing some old school science is very cool. With a modern twist it should be possible to build a stack of film to form a cube. Once retrieved and developed it could simply be scanned on a reasonable film scanner, and then massaged into a 3D volume. The longer and higher it gets on the flight the better. Sorting out the design, testing and validating of the experiment might take some effort, but it would be really nice to see.

    For a very British tie in, you can't do much better than this:

  50. lawndart


    Will you be reusing the PARIS release mechanism?

    How about a release on balloon burst method? The craft sits near-vertically nose upward on the side of the also-vertically-mounted payload box, supported by a pair of simple hooks around the trailing edge of the wings where they join the fuselage. Angled outwards slightly to ensure the craft clears the payload and balloon debris. The balloon is attached to a small box containing a spring plunger with the spring fully compressed by the payload's weight, with the payload box support lines suspended from the plunger. When the balloon bursts the spring opens, pushes the plunger upwards to complete an electrical circuit then trigger the rocket motor, filming, etc.

    Build in a couple of seconds delay to ensure any balloon still tethered to the payload box has time to roman candle in whatever atmosphere is available and off she goes.

    You'll need some method of preventing the plunger from completing the circuit during the bumping about at launch, though.

    "All GPS receivers capable of functioning above 18 kilometres (11 mi) altitude and 515 metres per second (1,001 kn)[50] are classified as munitions" so are hard to get hold of.

    Solid fuel is definitely the easiest option -- It is just a tube with fuel and a nozzle in one end. Don't use sugar+nitrate -- the caramel will foul your nozzle. A simple mixture is zinc+sulphur. You can (gently) heat it while in the tube to melt the sulphur to make the mixture solid. Since you have a plane, you should go for a slow burn rather than the fast burn appropriate for "pure" rockets.

    You could consider putting the rocket in front of the plane, so it pulls the plane rather than pushes it. It will make it easier to avoid spinning while the rocket is burning. A possibility would be a canard-style aircraft with a small control wing in front over the rocket and a wider wing aft (and slightly higher).

    Silly acronyms aside (important as they may be), it sounds like ultimately what you are going to end up with is some sort of mini auto piloted return vehicle.

    Or tiny Air launched cruise missile / glide bomb really, eh? ;)

    Unless you're really really really going out to town, I suspect you're not going to be able to carry enough fuel for any significant length of horizontal flight so I suspect you're probably going to end up with a glider with control surfaces. Maybe even some back up propulsion as necessary for course correction.

    I am wondering if you'll consider an automated return vehicle much like an RC Foamie. Would something that light suffer terribly by being completely at the mercy of the air currents up there? I can't recall how heavy PARIS was... Would electric props be suffiicient? Nitro will probably give you more performance but I am not sure about the weight compromise.

    Mmm... the more I think about it the more I think your return vehicle will probably get the most range out of being predominantly a glider but that means more complicated guidance, riding the currents, sort of like flying a real glider.

    But now back to the issue of of the rocket stage...

    Are you guys going to use it like more vertically like a ballistic missile, or launch the projectile at a more horizontal trajectory off the balloon (like an air launched cruise missile)?

    Between the helium balloon and the rocket stage(stages), how much height / range do you think you will get from each component respectively?

    I am wondering if the rocket bit is going to add much, if at all, to the overall range of this vehicle, if it's predominantly going to glide down and if it (and hence the rocket as well) is going to be somewhat limited in size.

  99. Poor Coco


    First off, I demand recognition for my original LOHAN recursive acronym ( even if its altitude objectives were contrary to a rockoon.

    Next off, as someone with experience building rocket-powered planes (Hasegawa F-104 plastic models with black powder engines) I can give you some tips:

    • The propellant you will want to use is APCP, ammonium chloride composite propellant — the stuff inside the Shuttle SRBs, for example. Its specific impulse is much higher than black powder.

    • To handle the problem of a stable low-speed launch, you need a rocket that will fly stably in what’s normally an unstable configuration, one with the CG far back. To accomplish this, you need to move the engines to the NOSE of the rocket, like the abort rockets on a human-carrying capsule.

    • To obtain thrust from the nose without incinerating the craft, place 3 or more engines in a conical configuration on a mast attached to the glider’s nose, with the engines firing at roughly 30° from the centreline. When the engines burn out, the mast separates (you can use explosives!) and the glider is left with an appropriate mass distribution for a controlled descent.

    The RC foamie suggestion is excellent; to obtain one strong and tough enough to withstand almost anything, you can skin the foam with 1/64" (0.4mm) aircraft-grade birch plywood, which is truly an astounding material. I have a sailplane wing I built out of it which is a pure monocoque structure: no foam inside, not even ribs, just some basswood stiffeners on the flat side and air.

    One person you certainly want to speak with is Tim Van Milligan of Apogee Components ( He is incredibly knowledgeable about rockets and I bet he’d love the chance to work with you guys.

      Thumb Up can use explosives!

      that's the clincher, surely?

    Am I the only one to notice

    The picture has an amazing resemblence to the titlular aircraft in Microprose' Stealth fighter game of the 80's?

      the titlular [sic] aircraft

      I think you'll find that 'eponymous' is the word you wanted to use.

    Forget the sub-orbital stuff

    Go all the way to low orbit and win the N-prize (in spirit, if not within the price parameters). Use a two-stage set-up if you have to. Maybe follow the Mythbusters and combine a sausage and NOx first stage with a solid-fuel second stage. That ought to grab some attention

    Mine's the one with the kielbasa and mortadella sticking out of the pocket.

    Surely you need to build a playmobil centrifuge & weightless-sim water tank to qualify the pilot?

    More thoughts of rocket boost-gliders

    I did a quick look around and spotted the Wowings Skua 1500 ( slope-glider. It has certain attractive properties; it’s designed to be fast; it has the stabilizers at mid-chord; it looks really cool.

    It would be nice if the wings could fold or swing back for the high-speed fight and then pop out just before the mast blows off, after the engines have burned out and some coasting time has elapsed. This would further reduce the frontal area; the wings could be locked back and then snap into place with a bungee cord or similar once the engines have burned out and the dynamic loading is low enough. Here’s another opportunity for explosive-bolt technology. :-)

    The more I consider the engine-mast idea the better it sounds. It could even be a mounting point for small, cheap video cameras feeding back to Flash storage on the plane (you can reasonably expect to lose the cameras along with the engine pod). The wires might have to pass right past, even wind around, the explosive charges to ensure they don’t foul the separation. BUT DAMN WHAT A VIDEO THAT WOULD MAKE!

    Not wanting to be a killjoy, but I'm fairly sure that "controlled by an autopilot which operates on GPS to fly the machine back to base" is illegal without a license. You can't operate a UAV above 400 feet and without being able to take manual control.

    Remember this?

    Just a thought

    Is anyone else worried that if you name the probe ELTON it might not head back to earth, that one might be more likely to head for Uranus? just a thought......

    Revell called, they want credit for the design

    First, I vote for Low Orbit Helium Aided Navigator.

    Second, your LOHAN concept illustration, for illustration purposes only, no doubt, nevertheless bears an uncanny resemblance to the stealth fighter plastic model that was being sold (here in the U.S. at least) after the plane's existence was known but before anyone in the public had seen one (must have been in the mid-80s). A co-incidence? I bet not.

    Kiwi homebrew cruise missile

    Slightly different engine choice but it may be interesting to look at the construction / electronics that were use in the home brew cruise missile put together here

    use of jigs to create foam blanks for coating with GRP look like the way to go for a cheap construction method.

    What about using a multi stage rocket stack to give more then 2 or 3 seconds of burn time?

    The question of flight control for the landing will be interesting especially as the aerodynamics of the craft will need to be understood to have any hope of "flying" the craft back to a known location. Again the Kiwi experience of flight control electronics could be interesting specifically the expertise needed to actually develop the aeronautic software.

    The other option is to not attempt a guided airframe but use passive methods such as helicoptering using stowed blades. It may be that the basic guidance controls for a helicoptering device are simpler and the idea of helicopters from space will send the tinfoil hat brigade to their bunkers!

    Getting it up there??

    (Oh, only Americans make successful things in garages. Hewlett Packard, and Apple spring to mind) The Brits build things in different places.

    1) The brick 'thunderbox' at the end of the garden...If you no longer have one, as it was destroyed in WW2, then I guess

    2) the allotment shed is the only place.

    There's a Russian supply ship going up soon. Don't s'pose El Reg has enough influence to persuade them to lob it out of the window? Or has Surrey Uni. got anything happening soonish? They're always cadging rides on something, then tossing out something tiny into orbit.

    Personally, I'd have a chat with Branson
