As a Certified flight instructor and having four years of aerospace science classes (I am a commercial aviation major) I can absolutely assure you that is not right. It all depends on the airfoil curves, the angle that wing is making with the oncoming wind and the weight that the airfoil has to lift. My grandpa's old J3 Cub (two seater and very light with big wings) can lift off in the 30 something mph range, the aircraft I routinely fly are in the upper 60s and transport aircraft may not takeoff until over 100 mph. I dont mean to rip apart what someone else says but there is alot of bad information out there when it comes to how aircraft fly and that is a striped down version of about a four hour lecture/discussion I would have with an actual student.
I agree that land missile is appropriate and wouldn't mind have it on my own 5th gen someday, ohhhh someday.....
