In 1986, Challenger broke apart 73 seconds after liftoff; 36 years later, a TV dive team found a shuttle artifact with 8-inch tiles off Florida

Divers found a large, tiled object while filming a documentary series. This unexpected discovery was later identified as space shuttle Challenger debris. NASA confirmed the find as the largest piece recovered in decades. The discovery serves as a poignant reminder of the 1986 tragedy. It also highlights the ongoing importance of spaceflight safety protocols.
