According to the BBC, a British Airways pilot made contact with Ireland's Shannon air traffic control to report a odd sighting and ask if there were any military exercises taking place in the area. The pilot said there were "multiple objects following the same sort of trajectory", and that they were "very bright where we were". "We saw a bright light and then it disappeared at a very high speed".
The pilot, flying from the Canadian city of Montreal to Heathrow, said there was a "very bright light" and the object had come up along the left side of the aircraft before it "rapidly veered to the north". Incredible audio has been released of the moment the pilots from three different flights had a close encounter with the "bright light". At 6:47 AM local time, a British Airways 787, using the callsign Speedbird 94, radioed in to ask if there were any military exercises going on in the area, which there were not.
The second pilot replied: "Glad it wasn't just me", to which Virgin 76 said: "No, eh, very interesting that one".
Another pilot also reported a sighting.

One claimed the UFO was travelling at an "astronomical" speed of at least Mach 2 (2,500 km/h), which is twice as fast as a commercial plane. He also suggested that the objects spotted in the skies could be meteors or other objects reentering the atmosphere.
