Light aircraft: Search continues for plane missing off Antrim coast
The underwater search for an aircraft missing off the coast of County Antrim has been described as looking for "a needle in a haystack".
Two people who were travelling in the light aircraft are feared to have died.
Debris was found on Friday but no further wreckage was found over the weekend.
Sonar equipment is being used to search under the water off the Antrim coast between Glenarm and Carn Point.
The Ikarus C42 disappeared after leaving City of Derry Airport for Scotland on Thursday.
Sean McCarry from the Community Rescue Service, told BBC Radio Ulster's Good Morning Ulster: "The focus would be to find any of the main fuselage which would be still intact.
"That would give us assistance in trying to recover whatever would be in the wreckage but also the Air Accident Investigation team would be able to come to a speedy conclusion.
"It is a massive area of water that needs searched, we have no entry point, we don't know what happened exactly.
"The search underwater is pretty much a needle in a haystack."
