 Pan Am carried 11 million passengers over 20 billion miles (32 billion km) in 1970, the year it revolutionized air travel with the first widebodied airliner.Pan Am was one of the first three airlines to sign options for the Aérospatiale-BAC Concorde, but like other airlines that took out options – with the exception of BOAC and Air France — it did not purchase the supersonic jet.Pan Am was the first US airline to sign for the Boeing 2707, the American supersonic transport (SST) project, with 15 delivery positions reserved; these aircraft never saw service after Congress voted against additional funding in 1971.
