I’ve been on it too, £120 for a taxi ride and then they stop and spin the engines up to full RPM for a while to let everyone experience the noise of those magnificent motors. It’s at East Kirby musuem near Horncastle. My motorbike club has an annual memorial get together every July there and they pull it out for that.
About six year ago a spitfire used to do a short 5 minute personal display, he used to break every rule in the book and fly over your heads at about 50ft, I’ll see if I can dig out a video of it, something spectacular to say the least
