Flight curve obtained during a parabolic flight. The jet plane ascended rapidly from 21 000 to 29 000 feet and then descended rapidly in a parabolic flight. Hypergravity (2G) was produced during the ascent and immediately before reaching the maximum point microgravity (µG) was obtained, and persisted for approximately 20 s. This was repeated 10 times during each flight. One parabolic flight was for approximately 100 s.
