never mind if it says it need to make enough thrust to go 100knots so in reality it is going 200knots it doesnt say it IS going 100knots. had to read it like 5 times

The plane's speed is irrelevant to the ground. The plane makes its thrust from air. It's how their engine works. The wheels barely generate any friction with the ground so it's still able to take off.

it cant fly at all

Haha.. think about it some more... it DOES take off.

i know right after i put that i put another post, can you add a delete you own post or something to the forum

:420what:

[Kelly087]

I read another variation where the conveyor belt moved against the plane with the same speed as the plane was moving, so if the plane was starting to move forward the conveyor belt would "stop" the plane from moving, which obviously it doesn't.

Sooooo.... if you watch Mythbusters I hear they're gonna be testing this out. I'm gonna record it if I can and watch it. Should be interesting.

You all must be Engineers and Physicists to overthink it that much.

[Kelly087]

Ha, yeah.... I am. Civil Engineering.

[skogey10]

Civil? Well that's just pretending to be an engineer, you should get this :O
