Shannon Air Traffic Control received a call from a British Airways pilot flying from Montreal to Heathrow over County Kerry at 6.47am on 9 November.
In a statement to CBS News, the Irish Aviation Authority said the reports will be "investigated under the normal confidential occurrence investigation process". The details are similar in some respects to reported sightings of unidentified flying objects over Oregon, Arizona, and NY, incidents that The War Zone was the first to report on.

The Irish Aviation Authority is investigating after the pilot of a flight from Montreal to Heathrow spotted a odd phenomenon while over the coast of Ireland.
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. It begins 17:50 and ends right after the 20:00 minute mark.
