I have a question on the 777. Did boeing ever consider using wingtips when they built the 777? I think it would have made that plane look even better! also they would get it more range. The 747-400 is the only boeing commerical plane to us wing tips. Why is that? Do they really work?

Actually, in it's infancy, there were winglets planned. But that was when the 777 was still being considered a stretched 767. Boeing isn't the biggest fans of winglets. At least they used to be. If you look at the 777 wing from a top view, you will notice that the tip is slightly angled outward. Boeing used this technology because in there eyes, winglets weren't necessary. They used winglets on the 744 because extending the wings more was impractical. They latest technology is the "raked wingtip". These are used on the 767-400 and on the coming 777-300ER and 777-200LR.

Well, I'll confess - I just don't see how a winglet can make one plane fly farther and not another. Why it makes the 737-800 and 747-400 go farther but won't benefit the 777 I cannot comprehend. Any help?
