Wizofoz,
Thanks for the props(as he tips his hat). I think you have read some of what I have with your comments about Raytheon and their lessons learned.
One thing that we should add though is the fact that the Premier 1 and the Hawker have metallic wings and the 7E7 is proposed to have composite wings and nacelles. Ask Southwest what they thought of their composite nacelles on the 737.
I really think you need some metal(at least the main spar) in a wing until our prediction capabilities mature.
You are correct though, if Boeing pulls it off, the 7e7 will be the new tentpole.
