1978 British Army Gazelle downing

On 17 February 1978, a British Army Gazelle helicopter, serial number XX404, went down near Jonesborough, County Armagh, Northern Ireland, after being fired at by a Provisional IRA unit from the South Armagh Brigade. The IRA unit was involved at the time in a gun battle with a Green Jackets observation post deployed in the area, and the helicopter was sent in to support the ground troops.
