The Concorde, the world’s only supersonic passenger aircraft, had a unique fuel system. Here are some fascinating details:

• The wings of the Concorde would droop at rest due to the weight of the fuel, which was later pumped into the main tanks for takeoff.

• During flight, the heat from air friction would expand the fuel, requiring a sophisticated thermal management system to maintain fuel stability.

This design allowed the Concorde to fly at twice the speed of sound, showcasing the incredible engineering feats in aviation history.
