Captain Roger Wills and copilot Mark Stuart were beginning their descent towards Manchester Airport in a Boeing 737. Seventeen minutes before touchdown, a mysterious, triangular shaped UFO flashed past the right hand side of the aircraft at a distance described as being "very close", so close, in fact, that the crew instinctively "ducked" in their seats.
This is an extract from the radio chatter between crew and the radar tower:
Pilot: "We just had something go down the RHS just above us very fast."
Control: "Well, there's nothing seen on the radar. Was it an aircraft?"
Pilot: "Well, it had lights; it went down the starboard side very quick [and] just slightly above us, yeah."
Control: "Keep an eye out for something, I can't see anything at all at the moment so, must have been very fast or gone down very quickly after it passed you I think."
Pilot: "Okay. Well, there you go!"
An eyewitness on the ground described the craft as triangular. However the CAA investigation failed to trace the cause of the incident with the possibility of a US Stealth aircraft straying off course being discounted.
