The only picture ever taken of a concord flying at mach 2 (1985)
"According to the photo description (available on ConcordePhotos.com), the dramatic picture in this post features ‘Concorde G-BOAG flying at supersonic speed and is the only picture ever taken of Concorde flying at Mach 2, 1350 mph. This unique image was taken from a Tornado fighter jet, which rendezvoused with Concorde for just four minutes over the Irish Sea in April 1985. The RAF Tornado, rapidly running out of fuel, was struggling to keep up with Concorde. Cruising at Mach 2, Concorde stretches six inches from her normal 204ft length. Due to the heating of the airframe, she reaches 127 °C at the nose and trailing edges but the special ‘high-reflectivity’ white paint helps reflect and radiate heat.’ "
