Forgive the link, but this was on the Falklands82 feed earlier today. The propellor of the Atlantic Conveyor is now a memorial, it's the fifth picture down.

I went to that cross on the hill and the chinook wreckage too. if memory serves me right 1 if not both of them were not from the actual war. The cross on the hill was helicopter shot down by our own forces after their radio transmisssions failed. And think the Chinook was just carrying soliders up to mount kent when fell out the sky. Could be wrong on both but been to them. Went to memorials at Goose Green, Galahad's at Fitzroy, San Carlos, even HMS Sheffield's on Sea Lion island.
