The Furthest Men from Home: Apollo 13.

Apollo 13 launched on April 11, 1970 with astronauts James Lovell, Fred Haise Jr. and John "Jack" Swigert. Intended to be the third mission to the moon, the astronauts had to scrap their plans and limp their way home after an oxygen tank exploded, which damaged the craft that would have landed them on the lunar surface. Edit: Damaged the command module. They could have landed, but wouldn't have been able to return home. (These events and their journey home are the basis of the 1995 hit movie, "Apollo 13", starring Tom Hanks.)

An interesting, yet often overlooked fact, is that these three men are the furthest humans to travel from Earth. Ever. The gerry-rigged return home had them swing further out into the moons orbit, which slung shot them back to Earth. This wider orbit pushed them out to the peak of 248,655 miles from Earth's surface, 60 miles further than any other mission.[1] One could say that this is trivial compared to other launches, considering they were only at a greater altitude by approximately 0.0002%, but nonetheless, still a fun fact.
