Date: 2025-01-27 09:51 pm (UTC)There was a documented incident in the late 70s/early 80s when a USAF SR-71 Blackbird, cruising over the Caribbean, was given a conflict alert by ATC (this was before TCAS was a thing) and told to turn to avoid traffic coming its way at 70,000 feet and Mach 2.
Yes, an SR-71 had to dodge a Concorde on a tourist trip.
While Concorde didn't usually go over Mach 2 in service -- fuel burn was too high, and they had to burn a lot of fuel just to run the air conditioning to stop the passengers from catching fire -- it's confirmed that during the test program, Brian Trubshaw (the chief test pilot) took one of the prototypes up to Mach 2.4 and held it there for half an hour.
And NATO air forces used regular Concorde flights as practice for intercepting Soviet supersonic bombers over the sea -- Tu-160 Blackjacks and Tu-23M Backfires -- because Concorde was a good match for their attack speed and altitude. It was also almost impossible to catch from astern.
