, and ends with the aircraft pointed down at a 30-degree angle. Fleet The company owns and operates a Boeing 727-227F Advanced, registration N794AJ, dubbed "G-FORCE ONE". It flies parabolic arcs similar to those of NASA's KC-135 reduced gravity aircraft. Zero-G research programs Zero-G’s Weightless Lab research program provides access to space environments so clients may achieve technological advances in biomedical and pharmaceutical research, fluid and fundamental physics, materials science, aerospace engineering, space exploration hardware and human space habitation. Past clients, such as Ball Aerospace & Technologies Corporation, California Institute of Technology, Harvard University, Jet Propulsion Laboratory, Mayo Clinic, Purdue University, and Tethers Unlimited, reported that parabolic flight are the first steps toward achieving their space research objectives and raising test readiness levels to better ensure experiments will succeed. Research flights for NASA NASA has a microgravity services contract with Zero-G, which provided the first flights under this contract on September 9 and 10, 2008. Flight time from Ellington Field near Johnson Space Center was provided for the FASTRACK Space Experiment Platform. The flights were funded by NASA's Strategic Capabilities and Assets Program.
