IMHO, The real heroes are the people at NASA who worked out how to get the three astronauts home safely.
"The Apollo 13 malfunction was caused by an explosion and rupture of oxygen tank no. 2 in the service module. The explosion ruptured a line or damaged a valve in the no. 1 oxygen tank, causing it to lose oxygen rapidly. The service module bay no.4 cover was blown off. All oxygen stores were lost within about 3 hours, along with loss of water, electrical power, and use of the propulsion system."

One day I'll learn to spell, returned, returned, returned. Would a passing mod please alter the title to spare me any more embarrassment. Ta.
