Airliner Junkie,
On a flight from London to Manchester last year, which lasts about 40 minutes by the way, I asked a flight attendant if I could have the flight plan after we had landed. 20 minutes after we were airbourne he came out of the flightdeck and said that the captain had invited me up for landing! It was fantastic, it was nighttime, and the first time I have ever sat in the sharp end.
Give it a go, you never know your luck!!
I just worked out how to use those things!!
Cheers
