Indeed - I have a few friends who fly or are learning to fly. I used to be able to take the 'trainees' up every once in a while and let them have a fly around, pass on a few tips and whatnot! Unfortunately that's no longer taking place, but I'm sure when they qualify the tables will turn and they can take me up for a spin.....
......or two
And no doubt they'll pass on a few things to me their instructor's taught them. That's one of the great things I love about aviation, it's one veeeery big learning experience, and generally, people help each other to enhance that experience
