Something's been zipping through the sky over Scotland.
Last December, an Airbus A320 passenger jet (the model pictured above, though that's not the exact plane) was flying at 4,000 feet and approaching a landing at Glasgow Airport when an object zipped underneath it, only about 300 feet away. The object flew so close that the two pilots who saw it said the risk of a collision was "high." One of the plane's pilots asked an air traffic controller at Glasgow Airport if the control tower had been "talking to anything in the area," and the controller said that not only were they not talking to other aircraft, but there were no other aircraft on radar.
"We seemed to only miss it by a couple of hundred feet, it went directly beneath us," one of the pilots said upon landing. "Wherever we were when we called it in it was within about 10 seconds. Couldn't tell what direction it was going but it went right underneath us."
The pilots who witnessed the object described it as blue, yellow and silver and "bigger than a balloon," but couldn't provide other details because it zipped past them before they had "really registered it." A search of the skies after the incident turned up nothing, and the pilots filed a report with the U.K. Airprox Board, which investigates near misses between aircraft.
In a recently released report on the incident, the Airprox Board concluded that it couldn't have been a glider or a weather balloon or an ultralight plane, as all would have likely been picked up by radar. So, what do they think it was? Well ... they don't know.
"Members were unable to reach a conclusion as to a likely candidate for the conflicting aircraft and it was therefore felt that the board had insufficient information to determine a Cause or Risk," the report said.
So, if you happen to be flying over Scotland, make sure you're ready to take evasive action against UFOs.
