Prior to the arrival of the Mercury Astronauts in August of 1959, the Johnsville Centrifuge was used for testing by X-15 pilots – including Neil Armstrong prior to his selection by NASA. To this day, the Johnsville Centrifuge holds the distinction of being the largest human centrifuge ever built. In addition to the Centrifuge, the developments at the Johnsville Naval Air Development Center (NADC) included pioneering work on GPS, transition lenses, ejection seats, and "black boxes".
Johnsville Centrifuge and Science MuseumAlthough the centrifuge itself (including its 4,000 HP electric motor) has been decommissioned for the past decade or so, it is in private hands and a science museum has opened in Warminster, Pennsylvania, with the historic centrifuge as its prime attraction. Also on display is a collection of artifacts including the gondola and contour couch used by Deke Slayton in the centrifuge, and the Mayo Tank – a precursor to the "Iron Maiden" that was used test the effectiveness of water as a buffer to high G forces.
