the lightning was one of the few planes to intercept a U2 i believe?
The official ceiling was a secret to the general public and low security RAF documents simply stated 60,000+ ft (18 000+ m), although it was well known within the RAF to be capable of much greater heights; the official maximum altitude mainly being determined by cockpit pressurisation reliability and safety. Recently the actual performance ceiling has been made public by the late Brian Carroll, a former RAF Lightning pilot and ex-Lightning Chief Examiner, who reports taking a Lightning F53 up to 87,300 feet
In 1984, during a major NATO exercise, Flt Lt Mike Hale intercepted an American U-2 at a height which they had previously considered safe from interception. Records show that Hale climbed to 88,000 ft (26,800 m) in his Lightning F3. Hale also participated in time-to-height and acceleration trials against F-104 Starfighters from Aalborg. He reports that the Lightnings won all races easily with the exception of the low level supersonic acceleration, which was a "dead heat".[3]
Carroll reports in a side-by-side comparison of the Lightning and the F-15C Eagle (which he also flew) that "acceleration in both was impressive, you have all seen the Lightning leap away once brakes are released, the Eagle was almost as good, and climb speed was rapidly achieved. Takeoff roll is between 2,000 & 3,000 feet [600 to 900m], depending upon military or maximum afterburner-powered takeoff. The Lightning was quicker off the ground, reaching 50 ft [15 m] height in a horizontal distance of 1,630 feet [500m]".
In British Airways trials in April 1985, Concorde was offered as a target to NATO fighters including F-15s, F-16s, F-14s, Mirages, F-104s - but only Lightning XR749, flown by Mike Hale and described by him as "a very hot ship, even for a Lightning", managed to overtake Concorde on a stern conversion intercept
