NASA Reduced Gravity Aircraft

The NASA Reduced Gravity Aircraft is an airplane that flies in 6 mile long parabolic arcs, first climbing in altitude, then falling in such a way that the flight path and speed correspond to that of an object without propulsion and not experiencing air friction. This can be done by using propulsion and steering such that air friction is compensated and nothing else. The end result is that people inside are not pushed towards the bottom or any other side of the plane,  they are temporarily weightless for a period of 25 seconds. Usually one flight lasts about two hours, in which 40 parabolas are flown.
