An inquest into the deaths of four Irish Coast Guard aircrew in the Rescue 116 helicopter crash has heard how the visibility in the moments before the crash was “very poor and dense”.
Rescue 116 crashed off Co Mayo at 12.46am on March 14 2017 during a search-and-rescue mission with four crew on board after it struck Blackrock Island, 12 miles off the Irish coast.
At the time of the accident the crew were offering support to an operation to airlift an injured man from a fishing trawler.
