Fairford, followed by Brize Norton, and then a host of airfields from Prestwick and Shannon to Chateauroux
In 1987 we also used Machrihanish because they were digging up the end of Prestwicks runway which made it too short for touch and go
In1998 we also used Porto as I think Chateauroux asked us to leave after too many noise complaints
Before we started base flying at Brize Norton there was a lot of negative opinion about it due to possible noise. The first day of training the airport was saturated with noise complaints, however what the local population did not know was that the Concorde had gone U/S and did not fly on that day. They could not see due to cloud cover but what they were complaining about were the RAF VC-10 in the circuit , and these aircraft had been training there for months with no complaints.
Shannon was always considered too risky for Concorde to base it self at for Base training, however in 1998 when things in N.Ireland had settled down a bit we did base a Concorde for a few days in Shannon for base training.
If I remember correctly during all the flight testing program at Fairford, BAC built a lay-by on the main road so that the public could watch the aircraft come and go free of charge. Apparently some bright spark bought himself a white coat and a roll of parking tickets and started charging people for parking. Now that is what you call
free enterprise
