Timeline of Supersonic Aircraft

The Concorde, a supersonic aircraft developed by Great Britain and France, was a significant advancement in air travel technology. It entered commercial service in 1976, offering fast transatlantic flights. Despite its innovative features, such as a fly-by-wire system, only 20 were built due to high costs. The Concorde faced challenges, including a fatal crash in 2000 and declining passenger numbers post-9/11, leading to its retirement in 2003.
