Shetland Chinook legacy remembered

The 25th anniversary of the worst offshore helicopter accident in Scotland's history.

Forty-five men died when their Chinook crashed into the sea off the southern tip of Shetland.

The event prompted workers begin to stand up for their rights for the first time.

Their campaign eventually led to the helicopters being withdrawn.
