Re: stolen from another forum
oh no, Madison! Its late sunday night so I forgive you! :^)
look at it another way - an F15 comes in at 200mph for a touch and go landing pass. It flies down on the runway, but maintains its airspeed, so the wheels touch the ground, then it throttles up and flys away.
Ok, so add your moving runway to the picture. The plane comes it at 200mph again, the wheels hit the runway, which is going backwards at 200 mph, so what happens? does the plane instantly stop, ignoring the laws of momentum?!
no, the wheels go BRIRP! and spin up to 400mph, the pilot hits the throttle again and does his 'touch and go', just as before.
The engines on a plane do not react off the runway. If they did, then how do planes in alaska with skis instead of wheels get off the ground?!
