Misconceptions: Physics of Flight

[romanza <romanza@MBOX3.SINGNET.COM.SG>]

Many texts give the explanation for lift of an aerofoil --- that the distance travelled by air on the upper surface is greater than the lower surface, and hence air must travel at a faster speed in order to "catch-up" with air on the lower surface.

This is quite a common misconception in explaning lift. But can someone enlighten me on how to give a more correct version without involving technical details like circulation, Joukouski Theorem etc.

Thanks.
