Sorry, But Flight Depends on Air Speed, not Ground Speed.

STILL MORE FROM THE AIRPLANE ON THE TREADMILL THINGY

You just can’t believe some of the amazingly stupid email I’ve been receiving from true pedigreed idiots over this airplane-on-a-treadmill bit.

OK .. now put away all rational thought. Try to imagine that you are absurdly ignorant and that you haven’t had a rational thought since third grade. You’re going to have to adopt this mental state to understand the argument that is being presented by people who were dismayed to see the airplane take off.

Ready? Here we go. They’re saying that the Mythbusters guys cheated because they allowed the airplane to move relative to the earth. Yeah … as hard as it is to accept, there are actually people out there who are so dismayingly stupid that they think that the rules of the game were that the airplane would not be allowed to roll forward when the propeller started turning.

How can our country survive this level of stupidity?

The thrust of an aircraft is against the air behind the aircraft not through the wheels. Therefore, it does not matter how fast the wheels are moving or in what direction they are rotating. The thrust applied will absolutely move the aircraft forward and once that happens it is a done deal. The plane flies no matter what is happening to the wheels from the conveyor.
