I'm thinking of the things I should consider before a flight.
Bergerie: I agree with your thoughts, and we could write volumes of all the under appreciated amount of thinking going through a commander's mind 'during' the flight. One sugar or 2; tea or coffee? Once they are sorted out we can then relax and address the plethora of information that continuously assaults the brain and needs filtering so that the tsunami of trivia doesn't mask those items that need careful attention.
As you say, some might not switch on the lights before the flight.
