### How Does the Zero G Plane Work?

Wondering how and why we'll be weightless inside the plane? Here's a great description...

"Typically, ZERO-G's plane, called G-FORCE-ONE, flies between 24,000 and 32,000 feet altitude. This gives the pilot enough room to maneuver the plane safely through its flight path. The plane's descent must start at a high altitude to provide enough distance for the pilot to safely pull out of a dive. As the plane climbs to the peak of its arc, the pilot orients it at a 45-degree angle. During the climb, the plane's acceleration and the force of gravity create a pull 1.8 times the strength of gravity alone -- passengers temporarily weigh nearly twice as much as normal.  As the plane goes over the top of the arc, the centrifugal force exerted on the plane and everything in it cancels out the gravitational force pulling downwards. At this point, passengers experience microgravity -- it feels as if you are weightless because only negligible gravitational forces are present. The sense of weightlessness lasts for about 30 seconds. Because the plane shields the passengers from the rush of air, they can experience a free fall without the interference of air resistance. The pilot pulls the plane out of the dive so that the dip between one arc and the next is at about 24,000 feet altitude. As the plane pulls out of the dive and begins to climb again, passengers again experience the force of 1.8 times that of gravity. The typical ZERO-G flight includes 15 of these parabolic arcs, while NASA flights may include up to 100." Source: HowStuffWorks

Tomorrow we'll be sharing photos of us setting up our experiment... stay tuned!
