A memorial to 10 American airmen who died in a crash on Belfast's Cavehill during World War II has been unveiled. The B-17 bomber went down in heavy fog 62 years ago after losing its bearings on the way to Nutt's Corner airport.

A plinth was unveiled in Belfast Zoo, near the crash site, on Thursday as a decommissioned B-17 flew over.

A film of how one crewman's wedding ring was found at the site decades later and returned to his widow, Closing the Ring, is being made.
