Nice one Dougie. I only ever did the Control Zone flying - in circles to keep our right to fly in circles over Berlin current. Cliff Foggo was on the one that collected the ND in the wing causing subsequent serious fuel leak. They must have missed us . . .
We went through Checkpoint Charlie with lots of cameras pointed at us (doubtless so Ashford had something to work with), but in the last year or two me and SWMBO stayed in the Hotel Angleterre (really), just up the road from the checkpoint.
We wandered through the area around the river and the Vopo shooting gallery - quite spooky.
Also, looking at the chariot on top of the Brandenburg Gate was weird as I'd only seen it from 'the West' and now I was in Unter den Linden looking towards 'the West'.
