Air India Flight 182
A Sikh extremist bomb brought down a Boeing 747 carrying 329 people over the Atlantic, roughly 250km southwest of Cork. The plane came down in deep water. No wreckage washed ashore. The closest mainland community was Ahakista. In 1992, a memorial garden was built here — a simple stone circle on the hillside overlooking the water. It's maintained, open, and there's no better place to stand and think about what happened than somewhere you can see the ocean where they fell.
