Okay, Houston, we've had a problem here
Jack Swigert (John Leonard Swigert, Jr.)
Died December 27, 1982 b. 1931
American astronaut. During the Apollo 13 mission he proclaimed, "Okay, Houston, we've had a problem here." Jim Lovell repeated the sentiment a few seconds later.
Note: The actual phrase was "Okay, Houston, we've had a problem here", spoken by Swigert. After being asked to repeat the transmission Jim Lovell responded with "Uh, Houston, we've had a problem". In the 1995 movie Apollo 13, the line was shortened to the more dramatic, "Houston, we have a problem".
