Zero G is one of those companies that I sincerely hope I get a chance to do business with one day. Their zero gravity experience is something I really hope to experience at least once in my life, but these new photos of Kate Upton posing for the Sports Illustrated Swimsuit Issue, while on a Zero G flight may hold me over until I can experience the flight myself.
To keep on the topic of Science & Space, let me let Zero G explain how the zero gravity flights work. Below is an excerpt from their website.
Aboard our specially modified Boeing 727, G-FORCE ONE, weightlessness is achieved by doing aerobatic maneuvers known as parabolas. Specially trained pilots perform these aerobatic maneuvers which are not simulated in any way. ZERO-G's passengers experience true weightlessness.
Before starting a parabola, G-FORCE ONE flies level to the horizon at an altitude of 24,000 feet. The pilots then begins to pull up, gradually increasing the angle of the aircraft to about 45 degrees to the horizon reaching an altitude of 34,000 feet. During this pull-up, passengers will feel the pull of 1.8 Gs. Next the plane is "pushed over" to create the zero gravity segment of the parabola. For the next 20-30 seconds everything in the plane is weightless. Next a gentle pull-out is started which allows the flyers to stabilize on the aircraft floor. This maneuver is repeated 12-15 times, each taking about ten miles of airspace to perform.
