So this thread is now in "Aviation History and Hostalgia", huh? In my opinion that's premature. Just two hours ago I saw one take off from JFK runway 31L. Departure at 13:35 local, i.e. 18:35 UT, bound for Seattle.
Due to thick fog/haze and very low ceiling, could only see it for about three seconds in blurry silhouette while it was straight overhead at maybe 500 meters. But the sound was as massive as ever!
All other aircraft were departing on 4L, so Concorde had no competition on 31L.
Of interest: sources tell me Concorde got clearance to take a route over sparsely inhabited sections of Canada, supersonic! Flight continues as I type this! Yay!
