A passenger jet came within 300ft of colliding with a UFO at Glasgow Airport.
The Airbus was 3,500ft above Baillieston on the outskirts of the Scottish city, when it came just seconds from crashing into a mystery object.
An investigation by the UK Airprox Board, which examines reports of near misses, could not explain the object but said: "The object passed directly beneath before either of the crew had time to take avoiding action or had 'really registered it' although they were both agreed that it appeared blue and yellow (or silver) in colour with a small frontal area but that it was 'bigger than a balloon.'"
The report included a transcript of a conversation between the A320 pilot and the Glasgow Aerodrome Controller once the aircraft was on the ground:
A320: "... we seemed to only miss it by a couple of hundred feet it went directly beneath us ...wherever we were when we called it in it was within about ten seconds"; "... couldn't tell what direction it was going but it went right underneath us"
EGPF: "do you suspect it might have been a glider or something like that"
A320: "well maybe a microlight ... it just looked too big for a balloon."
The Airprox report concluded: "Investigation of the available surveillance sources was unable to trace any activity matching that described by the A320 pilot. Additionally there was no other information to indicate the presence or otherwise of activity in the area."
Aviation expert David Learmount told the Daily Record: "Sometimes airplanes do get too close to each other and if we don't know how often it happens and under what circumstances, we can't reduce risk in future."
Meanwhile, Ron Halliday, UFO author told the newspaper: "This is exciting and intriguing.
"Here we have two professionally dedicated people who both reported seeing a UFO in daylight at such close proximity."
