OPERATION MAINBRACE sighting where six British pilots flying a formation of RAF jets above the North Sea observed a shiny sphere approaching from the direction of the fleet. The UFO eluded their pursuit and disappeared. When returning to base, one of the pilots looked back and saw the UFO following him.  He turned to chase it, but the UFO also turned and sped away.
