Nothing personal, friend, but I would not want my captain on a commercial flight having to do that...
See? I'm just the opposite. I want my captain on a flight doing whatever needs to be done to get the plane on the ground safely. If holding the flashlight in his mouth means the difference between seeing the instruments and not crashing vs. not seeing the instruments and crashing, then I'd rather see him use the funky way to hold a flashlight.

If you're flying in an Airbus you might not have a choice.
Would you rather the captain on your commercial flight didn't hold a flashlight in his mouth?
