RAFs Secret Hunt For Aliens

The secret papers obtained from the US military give an insight into an astonishing chain of events sparked by UFO sightings over East Anglia in 1956.
After receiving numerous calls reporting bright lights darting across the sky, fighters from RAF Lakenheath spent more than seven hours trying to shoot down the objects, which were picked up on army radar screens.
The classified documents were secured under the US Freedom of Information Act by Dave Clarke, an author researching the subject.
One US Air Force intelligence report described how 12 to 15 objects were picked up on radar screens on 13 August 1956. They were tracked for more than 50 miles. One object was logged travelling at 4,000mph. Operators making these radar sightings are of the opinion that malfunctions of equipment did not cause these radar sightings, the document said.
