Apollo 13 Flight Operations (Johnson Space Center)

During the April 1970 Apollo 13 mission, flight controllers at NASA's Mission Control in Houston managed the emergency response after an oxygen tank explosion, overseeing the procedures that returned the crew safely to Earth. The incident popularized the phrase "Houston, we've had a problem," a wording that is sometimes contrasted with the more commonly quoted variant in popular media; contemporary mission transcripts and reports document the transmissions and controller actions. Johnson Space Center's flight control teams' actions during Apollo 13 are documented in NASA mission transcripts and investigation reports.
