But I'm not an engineer, just a pilot who has never seen -curved- upward (or downward) wings. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
Tim,
what about the 777? That wingspan flexes upward a good bit when flying (something like 15 feet?). I'm sure they planned that (probably for stability), but it does look weird...
