The phrase comes from NASA's Apollo 13 mission in 1970, when the crew reported a serious oxygen tank failure to mission control in Houston, and it was later popularised by the 1995 film Apollo 13, in which Tom Hanks, playing commander Jim Lovell, delivers the line in its best-known form. The film turned a real emergency report into a cultural shorthand for trouble, and the clip has since spread through memes, reaction videos and edits, where its calm, official tone makes any small failure feel like a mission-critical disaster.
