This happened back in 1995 and the info is only now coming to light with the recent release of UFO secrets by the British gov.
"AN ALIEN spaceship "20 times the size of a football field" is among a string of bizarre UFO sightings included in top secret MoD files released for the first time today.
The huge craft was reported to the military after it was seen hovering above Manchester Airport in January 1995.
Incredibly, it was spotted the same day a British Airways pilot reported a "near miss" as he tried to land a Boeing 737 on the runway leading to a highly-classified MoD investigation.
Other sightings include a "cigar-shaped" object flying above Lancashire in February 1977 and in October 1980 two security police officers on patrol at RAF Woodbridge, Suffolk, saw a "strange, glowing object" in the woods.

"The object itself had a pulsing red light no top and a bank of blue lights underneath. The object was hovering or on legs. As the patrolmen approached, it manoeuvred through the trees and disappeared." "
