PHILIPPINE SEA, North Pacific Ocean -- Air Force pararescuemen flank Astronauts Neil A. Armstrong and David R. Scott, sitting in the Gemini 8 space craft, while awaiting the arrival of the recovery ship USS Leonard F. Mason after a splashdown in the Pacific Ocean March 16, 1966. Reservists from the 920th Rescue Wing at Patrick Air Force Base, Fla. provide first-response contingency medical and rescue support for all NASA shuttle launches. With the advent of the NASA's new capsule-based, manned-spaceflight program, Constellation, Air Force pararescuemen will once again greet astronauts on the high seas following splashdown.
