No? Really? Damn... I need to do more research then... I also thought that wind is made by trees swaying back and forth in the atomsphere...
When a fighter jet lines up at the end of the runway, it typically runs its engines up to full speed before releasing brakes. The speed of the wheels on the jet is equal to the speed of the runway below it (0 mph). The air coming out of the back of the engine is over 1000 mph, much faster than the aircraft needs to get airborne. If the myth is right, the aircraft should lift off!
And here is the argument you typically hear:
But wait, the brakes are set!!! That is why it doesn’t work!
So the second the pilot lets go of the brakes, the jet gets airborne?
No, it gets airborne when the speed through the air (not over the ground) reaches the point to cause enough lift over the wings to overcome gravity (the weight of the jet.)
The compressibility of air and temperature differences result in vast differences in one if you try to hold the other constant.
