It is hard to remember that absolutely everything that you say in the cockpit is taped. I think everybody has made some sort of "Airplane/Top Gun" (only for the real nerds) Reference at one time or another and its a harsh reality that this will be used against you in the media even if you do everything right.

Now I know that the crew in that accident probably should have made a different decision (I said "probably" because I wasn't there, so I can't second guess) I am not trying to relieve them of responsibility but such joking around at a critical phase of flight can change the accident from a "tragic mis-calculation" to "Pilot Negligence"
