I must admit my suspicion that there may have been a bit of hanky panky going on within the cockpit (pun intended) during that recent flight - the one where those two Northwest Airlines pilots overflew the Twin Cities by 150 miles.
Before considering my proposed, and admittedly wacky scenario, let's ponder the following facts.
1. Said one aviation safety consultant, "... In a car, this would be like missing your highway exit by 20 miles ..." What's that, 15 to 20 minutes? Hey -- that's not really much time.
2. They were in an older plane where the cockpit voice recorder was limited in length to the last 30 minutes of cockpit audio, a perfect alibi for a cockpit party. That makes it possible to automatically erase incriminating audio details.
Let's say that the moments of passion are over and the players (by the way, there were 3 flight attendants on that flight. Which means there may have been two in the cockpit, leaving one to mind the store) are buttoning up, zipping up, and whatever other tidying up chores are needed.
Reality sets in.
"Oh shit!", laments captain Jack. We just overshot our destination a few minutes ago".
"Not a problem, old buddy", co-pilot Larry quickly chimes in. "Turn this baby around, and nobody will know the difference by the time we land. A little human error is always possible, even for us professionals."
"Aren't you boys forgetting something", as attendant Betty quickly interrupts. "I can recall that our friend Susie here was doing more than her share of moaning and groaning, loud enough for that well-known recorder to prompt some embarrassing questions by the authorities."
"I know what we can do", Susie finally gets the floor. "Just blank the tape. My kid brother does that stuff on his computer all the time."
"Sorry to break the bad news here, kids, but we may be in a jam", captain Jack announces. "The bad news is the recorder is tamper-proof. The good news is that it can only capture the last 30 minutes - which means we need to record 30 minutes of quiet time. Starting now, the four of us must settle down and be all business. Larry, you need to calculate some turnaround location that'll guarantee a Minneapolis arrival no sooner than 30 minutes from now."
