Captain William Schaffner incident, 1970

When radar picked up an unidentified flying object over the North Sea, pilots quickly attempted to make contact. Captain William Schaffner intercepted a 'conical object' then all contact with him was lost. Three months later his plane was discovered undamaged on the seabed, but his body was never recovered. However, official reports eschewed the idea of an extra-terrestrial mystery, deeming the pilot's likely death being caused by flying too low over the sea.
