Apollo 13/Tear Jerker

"...Was it the door?"
 * Several points, but particularly the splashdown.
 * Considering this is a Ron Howard film, this is to be expected.
 * "We just lost the moon."
 * The sequence where Jim Lovell watches the Moon as 13 is speeding past it and imagines himself walking on the lunar surface. Goddamn, every man who flew in Apollo had earned the privilege to be on those flights, but if there was one among the corps who deserved to walk on the moon, it was Lovell.
 * The flashback at the begining of the film about the other crew caught in a fire.
