Comment on Why Cant Commercial Airplanes Go Faster? (2012)parentComments−vilhelm_s10yYes, both ori_b and I are asserting that you can't generate lift without sending air off in another direction. If you don't impart a net motion to the air, then by conservation of momentum you also can't generate a net lift.
