When the Falklands War blew up, the Chinook was seen as a vital asset to support the land forces, since the carriers had sailed (and were full to bursting with Harriers and Sea Kings anyway), four Chinooks were loaded on to (along with additional Harriers, Wessex helicopters, a mountain of spares), the requisitioned merchant container ship Atlantic Conveyor .
The Harriers took off and deployed to the carriers once in range, while the helicopters were prepared.
One Chinook, now serviceable, was airborne when Atlantic Conveyor , was hit by AM-39 Exocet missiles on the 25th of May, almost certainly, this extra large blip on a Super Etendard's radar screen was mistaken for one of the carriers.
This Chinook, call sign Bravo November though with no spares or tools, was to go on and provide vital support for the rest of the war.
In one case, 81 troops were squeezed aboard, the very first tasking had been to insert SAS into enemy territory.
Still in service, ZA718 has seen action in Northern Ireland, Kosovo, was one of 5 Chinooks in the heli assault from RN carriers, on the Al Faw in Iraq in 2003.
As well as more recent service in Afghanistan.
BBC Radio have told the story of this remarkable chopper and those who operated it here, (hurry, it might not be on there for long);
