The British Aerospace/Aerospatiale Concorde was the western's only Supersonic Airliner and one of just two to enter service, the other being the Tupolev TU-144, it cruised at Mach 2.02 at a cruise altitude of 50,000 to 60,000 ft, carrying a hundred passengers it operated only with British Airways and Air France having seven each.
The ones I've made are 1:1 in two liveries: British and Air France, registration are G-BOAC and F-BVFC, complete interior and cockpit.
