Keith's note: Alan Stern, Dan Durda [two videos] and ten other scientist took two rides in a centrifuge located at The NASTAR Center as part of a suborbital scientist training program held on 12 & 13 January 2010. On these runs the scientists were put through simulated rides aboard Virgin Galactic's SpaceShipTwo. The first flight was at 50% acceleration. The second flight was at 100% acceleration. You will note by his commentary that Dan Durda was determined to get on NASA Watch.
