France and Britain. Only 20 Concordes were ever built, and they were all sold to Air France and British Airways. http://en.wikipedia.org/wiki/Concorde Nov 30 07, 3:43 PM

Russia also had a varient. The Tupolev Tu-144 (NATO reporting name: Charger) was the first supersonic transport aircraft (SST), constructed under the direction of the Soviet Tupolev design bureau headed by Alexei Tupolev (1925–2001). Western observers nicknamed the plane Concordski (sometimes Konkordski), sounding like a Russian surname yet still very close to the Concorde, to which the Tu-144 was visually similar. A prototype first flew on 31 December 1968 near Moscow, two months before Concorde. The Tu-144 first broke the sound barrier on 5 June 1969, and on 15 July 1969 it became the first commercial transport to exceed Mach 2, and the fastest commercial airliner ever. http://en.wikipedia.org/wiki/Tupolev_Tu-144 Nov 30 07, 7:13 PM

There was also an American supersonic airliner built, but it either exploded or wouldn't pass safety regulations or something and was abandoned. This is thought to be why Concorde had trouble getting clearance to fly in the US - reckoned to be a case of sour grapes by many people here at the time. Dec 01 07, 2:28 PM

The Concorde often made flights across the Atlantic. So technically the United States did fly them, even if they didn't have a part in the airlines. Dec 01 07, 4:22 PM
