I fly people every now and again who pitch up and hang around at the airfield fence to watch the planes. Its some of the most rewarding flying I do. I was a keener once, walking miles to just look at empty airfields as a young lad, and later spending my student loan on a microlight.
I get a real buzz out of flying these people because I can still remember what a buzz it would have given me if someone had offered me a ride at a young age.
