Yes, I flew on Concorde. "The Concorde", using the definite article, is an expression that seems to have been confined to the USA for some reason (see past FT jocularity about this).

Regarding the seating it was 25 rows of 2+2 at First Class width and pitch, not really CR-700 size at all.

In the last year or two of service the cabin interiors were refitted at considerable cost, in fact the programme was never completed and a large quantity of materials remained unused when the aircraft was withdrawn. Among the refit was an LCD cabin speed display which just didn't show up on photographs, to the disappointment of the many who took photos of them at Mach 2.

The large Concorde model at the entrance to Heathrow was removed last month as airport owners BAA did an auction for the site and Emirates finally outbid British Airways for it. Well done BAA, in recognising your heritage and how your business evolved, you are absolute cretins. The cognoscenti will continue to refer to that point as the Concorde Roundabout.

One of the abiding memories of Concorde is when taxying along the ground. Everybody, absolutely everybody, ramp workers, people at the gate windows, employees of competing airlines, ALL had stopped what they were doing and were looking at you.
