Moby- how do you think a glider can become airborne?
It has to have wind over the wings.[/b]
And since it has no built-in means of propulsion, how does it get wind over its wings?[/b]
Either by a windy day, or another object pulling it.
Yes! So, let's say that this glider is being pulled by another object, possibly either a car, another airplane, or a really fast winch.

Let's say that the towing device is at the far end of the runway, not attached to the conveyor belt.

Place the glider on the conveyor belt, and start the towing device.

Does the glider take off?
That's flawed. You are now moving the glider in relation to the *calm* air - making it no longer calm to the glider.
