Well, I'll be dipped! I simply do not remember BN having anything to do with the Concorde! In 1979 I was running the largest travel agency in Colorado and don't remember ever hearing about it, though I must have at least read about it at some point. Strange. The Wikipedia article says they even "owned" the ac while flying between DFW and the east coast! That's even more bizarre! But then BN was a different sort of animal --- especially with Harding Lawrence in charge.

I was the guest of BA on the Concorde in the early 80s and flew it from IAD to LHR on a Halloween night. There were about 12 passengers on board. Best meal I have ever had on an airplane. Ate and drank from block to block --- 3.5 hours. When we got out over international waters they went super sonic and the acceleration literally compressed you into the seat. There was a Mach Counter on the bulkhead and it read .99 - 1.02 - .98 - 1.00 etc the whole trip. The ocean was so far down that it was a solid dark blue and it almost seemed the ac was upside down and you were looking at the sky thru those little windows. Great experience!
