This is reportedly footage of fighter pilot trainees experiencing simulated G forces. From the video, it seems likely Will won't be making the cut over at the Top Gun school. But now we finally understand why everyone was incredulous when Maverick and Goose reported their 4G negative dive with a MIG 28. With your eyes pushed back into your neck, it would probably be difficult to actually see such a maneuver if involved as a participant. Regardless, inspired by what we see here, we hope that in future pressings of the "Top Gun" DVD, extras will include Viper vomiting after a simulated fly-by.
