I uploaded this photo because last night I watched a re-run of the Smithsonian special on Concorde and towards the end of the program, the BA chief pilot made the most profound statement that brought him to tears, as it did with me- he said (not quoting word for word) "On the final arrival of Concorde to Heathrow, I watched 5 perfectly flyable airplanes sitting side by side, knowing they'll never fly another revenue passenger again"
