The first time I went higher than the local trees was in a T31 at Swansea on a winch launch with the ATC in 1971. I had a broken arm as I recall and thus wasn't allowed to play with anything.
It was still a fantastic experience and I loved every second of it. We didn't half laugh at the poor lad who threw up during the winch launch
When I showed my kids a dismantled T31 in Duxford and told them it was the first aeroplane I'd ever flown in, they looked at me like I'd started in WW1
