Not a stupid question, and probably apocryphal, but I pass on what a BA skipper told me recently:
Plane at cruising altitude, sunny day, everyone happy, little girl sends a note up to the flight deck:
"dear captain,
I just wanted to let you know how much I'm enjoying my first flight. Everyone's been so nice, lovely lunch with a hamburger and sweets and lots of coke, and the steward gave me a really nice goody bag with lots of interesting things in it.
I had a little sleep and then looked at the clouds and the land below, and started thinking about the great holiday we're going to have when we get there.
Yes, it's been a lovely flight, now please don't go and spoil it all by f?(&!ng up the landing.
Luv from cindy"
