- A phrase used to indicate a major problem; often humorously used for reporting any kind of problem.
The origin can be traced to the phrase in past tense ("Houston, we've had a problem here" ) that was used by the crew of the Apollo 13 moon flight, to report a major technical problem back to their Houston base. The phrase is normally misquoted as "Houston, we have a problem" as in the movie Apollo 13: "Houston, we have a problem". See Houston, We've Had a Problem (NASA). (Wiktionary)
