Houston, we have a problem

For Father's Day this year I gave my father a four DVD collection in a nice tin box called, "A Century of Flight: 100 Years of Aviation." He likes that kind of stuff, and so do I. I was flipping through the companion booklet, and saw a snippet about Apollo 13 I hadn't heard before. Apparently, when their almost fatal glitch happened, Lovell told Control, "Houston, we've had a problem." What an understatement! But that's not the phrase that has entered our collective consciousness. I think "Houston, we have a problem" works better for me.
