On 11 February 1990, a British Army Aerospatiale Gazelle helicopter, serial number ZB687, was flying near the Northern Ireland border between Augher in County Tyrone and Derrygorry in County Monaghan when heavy machine-gun fire from the ground struck it several times. Oil pressure dropped. The Gazelle was forced into an emergency landing in an open field, where it broke up on impact. Three of the four crew were injured. None were killed. The shootdown looks small in the long catalogue of Troubles incidents, an attack with no fatalities and a brief news cycle. But it was part of a deliberate evolution in IRA tactics, and within two years it had forced the British Army to redraw the entire architecture of its border surveillance.
