Re: What one has to remember is.......
Quite - the science is now pretty well sorted out...we know all about escape velocity, maximum dynamic load and many other things, that ensure we can launch into the ether and go beyond (towards infinity ?? ;-) )
It's the engineering that seems to have failed this time.
One wonders though, if we insist on astronaut safety systems, (that will save lives on an aborted launch), why this has not been implemented on payload launches?
Surely a sensible satellite company who wants a payload delivered into orbit safely, should only employ a firm who will be able to "save" an expensive payload from a RUD, if a rocket fails?
