Yep, that was it, Westbury and the white horse was magnificent. Actually, as you said, it made a great windsock as it wasn't far off the IP for the run in anyway.
Got to be honest, that's the only flying I really miss. I used to love Tac flying, getting paid for something I would have done for nothing (only joking).
I think the Scottac was best, out of Kinloss and low level all the way back to Lyneham via the Plain - didn't half make your car feel smooth when you left the car park
