Fed-up expert debunks theory of why planes fly

David Millward in London

An engineer has debunked one of the most commonly held myths in science -- why aircraft fly.

Aeroplanes fly because their wings cause the air pressure underneath to be greater than that above, lifting them into the air.

For years engineers have been frustrated by a theory which wrongly explained the change in pressure. The myth is commonly found in textbooks, and even Einstein was rumoured to have subscribed to it.

A Cambridge scientist became so fed up with the explanation that he created a minute-long video to lay it to rest.

The video, published on YouTube by Prof Holger Babinsky, seeks to explain in simple terms why the theory goes against the laws of physics. (© The Daily Telegraph, London)
