super spotter, read 747FOCALs reply and learn how to carry on a civilised debate whilst not sounding like a prat.
747, it may well be as you say, though knowledge of composites has come a long way since the Starship. Indeed rayethon has stated the the starship was worth it for the leasons learned and now applied on the Premier 1 and Hawker Horizon, both all-composite fuselages and certified.
I agree that the 7E7 (will it be the 787 do you think?) is risky, simply because it IS cutting edge. As such, though, my tip is that if it works it will put Boeing firmly in front of the race (not that it was ever anywhere else IMHO!).
