At NASA an aircraft has been termed, "The Weightless Wonder"
or, as it is better known, "The Vomit Comet". This
name stems from the fact that many people tend to get sick after
experiencing a zero-G environment.
For the occupants to experience zero-gravity the aircraft must
go through a series of parabolic maneuvers.
Starting at an altitude of 24,000 feet the plane climbs upward
at a 45-degree angle until it reaches its peak at around 32,000
feet and then it descends back down at a 45-degree angle. Zero
gravity is experienced as the plane starts to descend downward.
Zero gravity usually lasts anywhere from 15-30 seconds each
time. |
