The inaugural flight of the Concorde for the Braniff International Airways and British Airways joint SST service from Dallas-Fort Worth via Washington, DC, to London departed #onthisday in 1979. While the Concordes were flown at Mach 2 (over 1,300 mph) out over the Atlantic, Braniff could not exceed Mach 0.95 on the overland DFW–IAD leg. Service only lasted a year and a half and was canceled in June 1980.
