Three Irish experts will be sent to investigate the Saturday crash of the Russian Kogalymavia Airbus A321 in Egypt's Sinai Peninsula, the inspector of the Air Accident Investigation Unit of Ireland (AAIU) told Sputnik Monday. On Sunday, an Irish Aviation Authority representative told RIA Novosti that the Russian aircraft was registered in an Ireland-based office of US subsidiary company Wilmington Trust SP Services. "The Air Accident Investigation Unit (AAIU) of Ireland is sending two investigators to assist with the investigation. They will also be accompanied by an official from the Irish Aviation Authority. So there will be three individuals traveling," Leo Murray stated. The Kogalymavia (Metrojet) operator leased the aircraft from Wilmington Trust SP Services, which registered the Airbus A321 in 2012. French and German civil aviation teams, alongside an Airbus investigation team, are also expected to assist Russia's Interstate Aviation Committee in the inquiry. All 217 passengers and seven crew members aboard flight 9268, en route from the resort city of Sharm El-Sheikh to St. Petersburg, have been confirmed dead. The tragedy is the biggest civil aviation disaster in Russian and Soviet history.
