The program is designed to incorporate new technologies into NASA's flight programs and other commercial aerospace applications. Reduced-gravity
conditions can be simulated for periods of 25 seconds in an aircraft flying repeated parabolic trajectories.
Is this exposure of gravity related tech preparing us for releases on anti-gravity tech" ?? mebe methinks
Hate to burst your bubble, but that has nothing to do with "antigravity technology". It's just simple physics. When the jet flies towards Earth,
the passengers inside are essentially in free fall. The same as if they would have jumped out of it. You can get reduced gravity effects by going
down in a elevator or driving down a steep hill really fast in your car.
