A specially adapted trawler has joined a new search for the crew of the coastguard helicopter R116.
It will use sonar equipment and nets to trawl the seabed near Blackrock Island today where the chopper went down in March.
The bodies of Captains Dara Fitzpatrick and Mark Duffy have already been found – but there’s no trace of winchmen Paul Ormsby and Ciaran Smith.
