The Lightning had Mach 2 capability, but not for long, hardly enough to climb to Concorde level 60,000 ft and then do barrel rolls.
A Lightning F3 managed to make a stern intercept on a Concorde over the North Sea on 2nd April 1985 at Mach 2.2 at 57,000 feet. The pilot Mike Hale has written about it and the claim is backed up by an entry in the 11 Squadron ORB for that month. The fighter controller who set up the intercept is mentioned in the RAF Boulmer ORB. plus the fact that Boulmer controlled two Concorde v Lightning sorties that month. One interesting note in the Boulmer ORB is the route of the Concorde on the Hale Sortie. Moscow to Edinburgh. G-BOAC definitely landed at Edinburgh that day according to a spotters website and a Concorde did do a charter flight with passengers to Moscow on the 12th April 1985, so I suspect BA did do a trial flight to Moscow first. It would be interesting to know what the Concorde's route was.
