The Concorde is a supersonic passenger jet airliner that flew from 1976 to 2003. It flew at speeds over Mach 2; it was about 2.5 times as fast as a modern passenger jet like the Boeing 747.
The Concorde's streamlined shape was aerodynamically efficient, but it obstructed the pilot's view during taxi, takeoff, and landing. Therefore, it had a droop nose; the nose would be lowered 5° for taxi and takeoff, and 12.5° for landing.

The Concorde had a good safety record. It only had one fatal crash, from a fire caused by running over a strip of titanium alloy during takeoff. There wasn't a great technical reason to retire it. However, it wasn't cheap; Concorde flights were priced a tier above first class. Some think that it was retired simply because it was more profitable for airlines to transport people in subsonic passenger jets.
