RTE have a still picture of the heli (landing/taking off) apparently moments before the accident.Regardless of what went before, Bettystown beach is big and long.
Why depart over a built up area? Was it necessary? Could this incident have been avoided by a different departure route with speculated engine failure resulting in forced landing to the beach? Doesn't look from the wreckage there was a lot of speed involved at final impact(thankfully).
I know hindsight is a wonderful thing.
Glad all ok.
