Re the discussion on superjumbos, I think the question came up once before regarding a stretched 747. I'm not an engineer, but am familiar somewhat with what goes into a "simple" stretch. I seem to remember reading (in AW&ST?) that the 747-400 couldn't simply be stretched without a totally new wing. DOes anyone have any firm grip on this? I'm sure they could probably to an upper deck stretch to some extent without a new wing, but that wouldn't gain a huge number of seats. Can the fuselage really be stretched an appreciable amount and still fly on the same wing? And how does the growth in weight associated with such a stretch affect the footprint of the airplane on the ground? We obviously have the engine technology to go along with such a stretch (GE90 powered 747s?), but could the old wing take an engine in the 70,000 lb thrust class? Any view on this would be appreciated... Jennings Heilig My boss said I have to put something down here... and I'm the boss.
