As a novice radio controlled plane pilot this did not seem to be correct. e.g. it failed to deal with planes flying upside down or on their side. I googled and quickly found that this is the "Equal Transit Time" fairy tale. Here is the NASA explanation:

Now have a look at what RC planes can do with completely _flat_ wings:

rather amazing, or not? It's also partly all down to the angle of attack, or more accurately the "decalage". Here is a fairly complete explanation of that topic:

I suggest that the video be withdrawn to keep the NakedScientists standards top of the line.
