Re: The end of an era
Sorry to have to correct you, but yes, Airbus *did* have a freight version in mind when the plane was designed. But the decision was taken to stop work on the freight version when it became clear that the passenger version was running horribly late (thanks to various things, like the mis-matched cable runs, the additional weight, etc etc). Fedex was one of the great proponents of the A380F, as was UPS, and both cancelled their orders when it became clear that Airbus wasn't going to work on an F version for a long while yet. And when all those orders disappeared, along went Airbus's desire to dig into building one. The primary problem with the A380 was the middle and the upper floor, not the cockpit position in particular. Strengthening both would have reduced the total freight it could carry (because of increased weight) and the economic case for it disappeared.
And no, the 747 was *not* designed as a freighter first. Juan Trippe (PAN-AM's famous leader) didn't ask for a freight plane, he wanted passenger jets that doubled the capacity of the existing 707s. But Joe Sutter, the 'father of the 747', said that it would make sense to use the broad design cues of the CX-HLS project (which Boeing lost to Lockheed and which Lockheed developed to the C-5A Galaxy) because keeping the cockpit up and out of the way would make the plane ideal for freight also, and that the area behind the cockpit could be used for other things, like a lounge, which PAN-AM did have originally. But when you then realise that you can shove more self-loading freight up in there, why not! Initial design studies had some versions of the 747 with the cockpit in various locations, including the "ant eater", which did what the Airbus Beluga and Beluga XL (based on the A300 and the A330 respectively) do now, i.e. a lowered cockpit. The B777 shows that even with the cockpit in the way, you can still load big things for the vast majority of cargo cases, and the 747 DreamLifter (designed and built by Evergreen) didn't use the nose either, but rather had the *tail* hinged for those 787 fuselage sections coming from Italy and Japan.
That said, the 747 was revolutionary. It made modern air travel possible because of scale of economy, and it makes outsized air freight possible in a way that 'normal' air freight (of which the majority is transported in the belly cargo holds of the world's passenger airliners) can't. The older 747s and the modern B777F are close in total weight capacity they can lift, the modern 8F is more a step change in fuel economy (given it uses the GE-nx) than total volume being lifted. :)
The old bird will be missed by those who flew them. It was nice to see a Magma 747 BCF on the tarmac in virtual touching distance the other week... if only the pesky apron staff hadn't been around... ;-)
