Caption: A KC-135 once used as the Zero-G Trainer for Astronauts
Additional Description: Sometimes called "The Weightless Wonder," more often called the "Vomit Comet" this is NASA's KC-135A aircraft, which was used to train astronauts and test equipment for spaceflight. The aircraft, nicknamed "the Vomit Comet," flew specific flight paths to mimic various states of microgravity. The KC-135A could fly a series of large parabolic arcs, allowing passengers to experience about 25 seconds of microgravity at the top. Elsewhere along the flight, the aircraft could give the sensation of approximately two times the force of gravity on Earth. The marker is on the other side of the display. If you look carefully you can see the back of the marker below the nose wheels.
