Mountjoy Prison Helicopter Escape

Date: October 31, 1973 • Location: Drumcondra, Ireland

Three Provisional Irish Republican Army members escaped from Mountjoy Prison in Dublin aboard a hijacked helicopter that landed in the prison's exercise yard.

The Provisional Irish Republican Army, officially known as the Irish Republican Army and informally known as the Provos, was an Irish republican paramilitary force that sought to end British rule in Northern Ireland, facilitate Irish reunification and bring about an independent socialist republic, which would encompass all of Ireland. It was the most active republican paramilitary group during the Troubles. It argued that the all-island Irish Republic continued to exist, and it saw itself as that state's army, the sole legitimate successor to the original IRA from the Irish War of Independence. It was designated a terrorist organisation in the United Kingdom and an unlawful organisation in the Republic of Ireland, both of whose authority it rejected.
