Ireland has a relatively strong aviation safety record, but there have been several notable crashes in its history. One of the most famous and mysterious was the Aer Lingus Flight 712 crash in 1968, where a Vickers Viscount plunged into the sea off Tuskar Rock, killing all 61 people on board; the cause remains a subject of debate today. In 1985, the tragic bombing of Air India Flight 182 occurred in Irish-controlled airspace off the coast of County Cork, resulting in 329 fatalities; the wreckage was recovered from the Atlantic seabed in a massive international operation. More recently, in 2011, a Manx2 flight crashed at Cork Airport during a third attempt to land in thick fog, resulting in six deaths. It is important to distinguish between real-world history and "fictional" lists often found in online "alternate history" wikis (like "Starliner 1561" or "SkySuisse 482"), which did not actually occur. Ireland’s Air Accident Investigation Unit (AAIU) is responsible for investigating all real incidents to ensure that Irish airspace remains among the safest in the world.
