On Friday morning just before 7am, a British Airways pilot contacted Shannon Air Traffic Control to ask if there were any military exercises taking place in their airspace.
Another pilot also reported a sighting.
She claimed that it did not appear to be on a collision course with the plane but admitted she was still "wondering" what it could be.
The controller replied to the pilot that there were no military exercises taking place, to which the pilot replied: "Okay, it was travelling so fast that you can no longer see it".

The first sighting was registered by a British Airways pilot Friday, November 9, at approximately 6:47 a.m. local time, while flying over the southwest coast of Ireland, with the sudden sight leaving him at a loss for words.
