This photo was taken in April of 1985 over the Irish Sea by Adrian Meredith who was flying in a Royal Air Force Tornado fighter jet and it’s the only photo of a Concorde flying at supersonic speed. Even though the Tornado is capable of matching the Concorde’s cruising speed, it could only do it for so long before it would run out of fuel at the rate it consumption with its afterburners. Several attempts were made to take the photo in fact, and eventually the Concorde had to slow down from Mach 2 to Mach 1.5 so that the Tornado crew could get the shot. The Tornado was stripped of everything to get it up to that speed for as long as possible.
After racing to intercept the Concorde and making several attempts to get the shot, they finally got it just in time before the struggling Tornado trying to keep up had to break off; while the Concorde just cruised along toward New York.
