Notification of the request and the reason for an emergency landing on 3 June 2018 by a US military aircraft, a McDonnell Douglas KC-10A Extender, was conveyed to my Department, via the Department’s Duty Officer, following the declaration of an emergency by the aircrew and prior to the landing in Shannon taking place. The Duty Officer in turn was in immediate contact with An Garda Síochána and Shannon Airport. The US Embassy subsequently confirmed to my Department in writing that the aircraft in question was unarmed, did not carry any arms, ammunition or explosives, was not engaged in intelligence gathering and that the requested flight did not form part of any military operations or exercises.
