Here's your proof

The Brooklands Concorde G-BBDG, the first British production model.
Me in the cockpit of the real Concorde after my Simulator session
The certificate we each got to commemorate the event! It was an absolutely fantastic experience with great stories from our Concorde Captain Terry Henderson and the simulator is superb, an absolutely faithful replica of a real Concorde cockpit and most of the instruments work too. The simulated view software is MSFS so it felt (and looked) familiar and she handled beautifully.
The flight in the simulator itself is captured on video so all I have to do now is work out how to transfer it onto my PC and then upload it somewhere to view - never done that before... Any hints, anyone?
