"How feasible does the Miles SST seem to you folks?"
I would have expected aerodynamical problems, as the supersonic flight regime
to my opinion still wasn't fully understood in 1943. If it would have encountered
the same fatigue problems, as the Comet, I'm not sure, as the principal reason,
AFAIK was, that the strengthening frames around the windows weren't only glued,
but additionally rivetted. And the holes for those rivets later were the cause for
fatigue cracks. Tragically, it already was known, that additional rivetting of bonded
parts actually weakend the joint, but that knowledge hadn't come through to
de Havilland. That Miles would have made the same mistake cannot be taken for
granted, I think.
