COMET is a privately held aeronautics entertainment and tourism company that’s developed the world’s first zero gravity aircraft called G-Flight. COMET is proud to be able to offer the only commercial opportunity on Earth for individuals to experience true weightlessness without going to space.

COMET is in their final stage of testing G-Flight, and is expected to start offering the exhilarating adventure of weightlessness to the general public starting in May 2021. G-Flight will tour and make several stops in major US cities to offer the general public the true lifetime experience of weightlessness.

Space travel may still be a few years off, but COMET is making sure you get a taste of that zero-gravity life in 2021. Based out of Santa Barbara, California, COMET has been developing, testing, and perfecting the zero gravity aircraft for over 12 years. After years of meticulous procedures and safety regulations, co-founders Dr. Luis Ortiz, veteran astronaut Melissa Carson, and NASA engineer Todor Relev acquired FAA approval for G-Flight, a specially modified Boeing 727-200, to take passengers on commercial parabolic flights.

In August 2004, G-Flight flew its first commercial flight operating under the same safety standards of all major air carriers and established its place into the extreme tourism industry as the first and only commercial zero gravity flight for the general public. Apart from commercial flights, G-Flight also provides research and educational flights.

G-Flight is a modified Boeing 727-200 with an upgraded hydraulic system that allows for continuous hydraulic pressure during parabolic performance. The modification, along with the addition of accelerometers in the cockpit, were tested and approved by the FAA. No structural modifications were made to the aircraft’s interior or exterior. The interior of G-Flight has been altered to allow for maximum floating space.

The seats are located in the rear of the plane. The floating area is divided into sections and padded from floor to ceiling with one rope running down each side of the plane. The parabolic flight is achieved when the pilot first gathers momentum and then starts a rapid ascent, which results in a force about twice the normal gravitational force of the earth.

G-Flight flies in FAA-designated airspace blocks approximately 100 miles long and ten miles wide. The process starts with the aircraft flying level with the horizon at an altitude of 24,000 feet. The pilots then gradually increase the angle of the aircraft to about 45° relative to the horizon until reaching an altitude of 32,000 feet. During this phase, passengers feel the pull of 1.8 Gs. Next, the plane pushes over the top of the parabolic arc and the zero-gravity phase begins. For the next 20-30 seconds, everything in the plane is weightless.

Finally, the plane gently pulls out of the maneuver, allowing flyers to gradually return to the floor of the aircraft. The maneuver is flown 15 times over the course of the flight, each taking about ten miles of airspace to perform. In addition to zero gravity, flyers aboard G-Flight experience Lunar gravity (one sixth your weight) and Martian gravity (one third your weight), achieved by flying a wider arc over the top of the parabola. On a typical flight, parabolas are flown in sets of three to five, with short periods of level flight between each set.
