Debris from the Challenger shuttle disaster which exploded two minutes after take-off and killed all seven crew members has been found off the Florida coast.
The Space Shuttle Challenger exploded in 1986 killing all seven crew members on board after it malfunctioned just 73 seconds after taking-off.
However, a TV documentary crew searching for Second World War aircraft wreckage found the debris after noticing a huge human-made object on the seafloor.
