Haise, Fred Wallace, Jr. (1933-...), served as lunar module pilot of the United States Apollo 13 space flight in April 1970. About 56 hours after the flight began, an explosion caused by a short circuit severely damaged the systems that supplied electricity and oxygen to the command module. Haise and his two fellow astronauts retreated into the lunar module, which had enough oxygen to keep them alive during their return to the earth. In 1977, Haise flew the first manned space shuttle test flight with Gordon Fullerton.
