Whilst traditional subsonic jetliners usually reach a cruising altitude of thirty to thirty-five thousand feet, Concorde nearly doubled that, cruising at an altitude of between fifty-five and sixty thousand feet. British Airways claimed that “only astronauts flew higher,” and that the altitude puts you far above the weather, allowing for an extremely smooth, turbulence-free flight. At this high altitude, the sky was an intense indigo blue, and the view was truly remarkable. Looking out the window, one could make out the gradual curve of the earth below, and it was even more evident when viewed from inside the cabin over the span of a few windows.
Here are some photos of this unique view from Concorde, flying on “the edge of space”
