Concorde with Concorde beating other British design icons such as the Mini, mini skirt, Jaguar E-Type, Tube map, the World Wide Web, K2 telephone box and the Supermarine Spitfire. The heads of France and the United Kingdom flew Concorde many times. Presidents Georges Pompidou, Valéry Giscard d'Estaing and François Mitterrand regularly used Concorde as French flagman aircraft in foreign visits. Queen Elizabeth II and Prime Ministers Edward Heath, Jim Callaghan, Margaret Thatcher, John Major and Tony Blair took Concorde in some charter flights such as the Queen's trips to Barbados on her Silver Jubilee in 1977, in 1987 and in 2003,
Concorde altitude winds compared to those at standard cruising altitudes, these dedicated SST tracks had fixed co-ordinates, unlike the standard routes at lower altitudes, whose co-ordinates are replotted twice daily based on forecast weather patterns (jetstreams). Concorde would also be cleared in a block, allowing for a slow climb from 45,000 to during the oceanic crossing as the fuel load gradually decreased. In regular service, Concorde employed an efficient "cruise-climb" flight profile following take-off. The delta-shaped wings required Concorde to adopt a higher angle of attack at low speeds than conventional aircraft, but it allowed the formation of large low pressure
