I did my flight a few years ago from Biggin Hill. A fabulous experience. The safety briefing videos are hilarious- it’s almost as though they are trying to scare you out of flying.
Favourite moment was when I flew a Barrel Roll over the M25. I wasn’t charged extra to see the back of my helmet- you can just about hear me over the engine when I complete the Roll. I think it was just a shout of elation!
Utter respect to the people who flew these in earnest.
