"When the Apollo 13 Command Module was examined after its return, it was found that the crew had tried to wire up a manual deployment switch for the recovery parachutes. However - they had in fact wired the switch to the parachute jettison control. If they had decided to use their jury-rigged manual override they would have in reality released the parachutes from the command module and plunged to their deaths in the ocean below."

"Finally, the failure of the Apollo 13 mission meant that the Lunar Module reentered the atmosphere carrying an RTG and burnt up over Fiji. The RTG itself survived reentry of the Earth's atmosphere intact, and plunged into the Tonga trench in the Pacific Ocean. The US Department of Energy has conducted seawater tests and determined that the graphite casing, which was designed to withstand reentry, is stable and no release of plutonium should occur. Subsequent investigations have found no increase in the natural background radiation in the area. The Apollo 13 accident represents an extreme scenario due to the high re-entry velocities of the craft returning from cislunar space. This accident has served to validate the design of later-generation RTGs as highly safe."

Apollo 13 is a great example of bad luck and how intelligence, improvisation and guts can turn it into good luck.

My dad's friend H. David Reed was the flight dynamics officer for the Apollo missions. Incredibly interesting man to talk to.

Amazes me the sheer precision and focus all of these people have. It's a world above mine.

Their "accident" had nothing to do with bad luck. It was sheer stupidity on the part of several engineers. Using a 56 volt power supply to feed a 28 volt heater over a long distance can and did lead to damaged wiring. sam

Kills me inside every time someone claims we never went to the moon, much less space. Fortunately I can take comfort in John Glenn kicking the **** out of someone who said that.

Gods bless that man.

Which begs the question...Why wasn't a manual deployment switch for the recovery parachutes pre-installed? I would think a space craft from the 1960's would manual switches as an backup for every critical automated system.

I dunno... that would probably be a lot of switches!
