Here's the real story (from The Illustrated History of NASA: Anniversary Edition): Apollo 13 was to be the second lunar misson. The Saturn V was launched on 11 April 1970 and the first 55 hours and 55 minutes proceeded without problems. The spacecraft was 320,000 km from the earth and still accelerating towards the moon. Having just finished a telecast to Earth, the crew - John Swigert, Fred Haise, and James Lovell - were clearing [sic] up. Suddenly there was a loud bang, the spacecraft vibrated and within seconds the master alarm sounded. A liquid oxygen tank in the service module had exploded, and had destroyed the fuel cells which supplied power to the spacecraft. Also, the oxygen supply was cut off. The service module, including its propulsion motor was dead. The command module had a backup battery pack, but that would be need for reentry. In any case it had a life of only 10 hours, and Apollo 13 was 87 hours from home. The crews salvation reste with the lunar module Aquarius. For the next three days they had to rely on its limited power supply, its oxygen, and its engines to get them back home. They fired the LM's decent engine to change Apollo's trajectory into one that would swing them around the Moon and direct them back to Earth. During the return journey, the temperature in the crippled spacecraft continued to fall. During the final part of the journey, the crew got a look at the service module after it had been cut loose. A whole side had been blased away. Afterwords, then President Nixon said "You did not reach the Moon, but you reached the hearts of millons of people on Earth." I stand by my previous statements though. Manned space missions are high profile undertakings. The US government, not just NASA would be held accountable if ever they tried to leave anyone in space, just for the *possible* retrevial of a spacecraft.
