THIS IS THE "BLACK KNIGHT" satellite. It was officially discovered in orbit around Earth in the 1950's. It is said by some astronomers to put out a repetitive electronic signal. NASA says it is about 12,000 years old. Hmmmm, How would they know that? I am sure NASA have sent the Space Shuttle to its location and investigated it very closely. Someone should send a Freedom of Information Request to NASA and ask for the complete file of the "Black Knight". I bet it would be interesting reading.
