Up to 150 divers from around Ireland will lend a helping hand in locating the missing crew members of the doomed Rescue 116 aircraft.
Rescue 116 crashed on the slopes of Blackrock Island on March 14, causing total hull loss and the death of all its four crew. Winch operators Paul Ormsby and Ciarán Smith have not yet been located.
Divers will be in the water on Saturday morning. The search has been organized by West Cork Underwater Search and Rescue.
