Enroute Airbus A380 wake flips Challenger business jet upside down

Thanks for this. I read a million explanations of how airfoils worked as a boy and they all said the air had to travel faster over the top surface to catch up. Why does it have to catch up? I would scream internally. I'm stunned to find it was never true.

This [1] is one of the most comprehensive examinations of lift, written in layman terms.

You can read the HN discussion here [2], since this appeared on the front page a week ago, much to my surprise [3].

Probably like the Bohr model in Chemistry, it's an easy way to introduce the concept. Frankly I was under the impression it was true, too, and my dad was a small-plane pilot.

The Bohr model at least has simplicity going for it, and it's close enough to explain most things that are relevant to chemistry.

For aircraft lift, "equal transit time" is not easier to understand than "an angled wing pushes air down, because of conservation of momentum that pushes the aircraft up".
