A relative of the President McAleese is among the six people killed after a plane from Belfast crashed in fog at Cork Airport this morning.
The Manx2 commuter flight with 10 passengers and two crew on board crashed on the runway on its third attempt to land just before 1000 GMT.
Brendan McAleese, a cousin of Mary McAleese’s husband, was killed.
The other victims were said to be two Northern Ireland businessmen, a Briton, a Spanish pilot and British co-pilot.
Mr McAleese owned the Central Laundries business in Cookstown, Co Tyrone, and was married with a young family.
Another of those killed was Pat Cullinan, originally from Omagh, Co Tyrone, and a partner in accountancy firm KPMG in Belfast.
A third victim was named as Captain Michael Evans, deputy harbour commissioner in Belfast.
Irish, British and Spanish passport-holders were on board the aircraft which was flying between the two cities as part of a scheduled daily service. All their families have been informed.
The six injured are being treated at Cork University Hospital. Four are said to be in a serious condition. The other two are described as being “comfortable”.
