Segment of Challenger's right wing unloaded at Kennedy Space Center Logistics Facility. It was located and recovered by Navy divers from the Opportune about 12 nautical miles northeast of Cape Canaveral in 70 feet of water. Space Shuttle Challenger exploded 73 seconds after lift-off from Kennedy Space Centre, Florida, USA on 28 January 1986. The explosion occurred as a result of a failure of one of the O-rings in a seal on one of the booster rockets. A subsequent leakage of fuel triggered the explosion that killed all seven crew members.
