nose-down attitude at take-off B-52 ground effect
(Dumb question? er...question sequence)
Doesn't something called "ground effect" enhance lift below some very low altitude? So wouldn't that, plus lower Cd due to gear up, make very low flight above a runway a good place to accelerate? And wouldn't a low-nose attitude sort of facilitate this low flat flight regime? And reduce tire wear, in comparison to developing pre-rotation velocity in normal fashion?
