On the civil ramp 1979. The Queen was carrying out a Middle East tour and had just arrived from Riyadh, hence the red carpet. The chap in the beige suit walking to the aircraft is one of her bodyguards. A special mod was the royal standard, which was flown out of the captain's side window when the Queen was on board and Concorde was taxying slowly.
A beautiful aircraft what a shame it no longer flies.
