The fast runs and runs are done by Ex RAF pilots who used to operate them in Service, they are far from cowboys with toys and they all take things very very seriously. As for anyone getting in one and stealing it, the place is like Fort Knox with dog patrols etc as it doubles as a car storage facility for major manufacturers new stock and were talking the higher end, even the police use it for storage. A lot of the aircraft when sold were demilitarised with wiring looms etc cut
Please don't get me wrong, did not mean to that these guys would be cowboys. Just meant that if the RAF got short of aircraft that with all that kit and skills you guys have you would be able to offer your services, either in combat or a training support role. Shame none of them fly. Certainly did not mean stealing any of them. If I owned one I'd hope the security was high. Excellent investment, probably better return than putting your money in a bank.
