Airplanes Spontaneously Taking Off During A Microburst At An Airport

That's why you're supposed to tie them down.

IF this is real, how come the planes fly off in opposite directions?

the post is wrong. They are taking off without running. The engine was on and there are a pilot inside.

This is from the U.S. Air Force academy glider school (KAFF). They were trying to get the gliders towed inside before the weather hit. The tow planes (sky trains) had pilots in them and were un-tied. The skilled instructor pilots in the sky trains did a fantastic job saving the planes. It's fortunate that non of the gliders had been attached by cable to the sky trains before the micro burst hit.
