It seems the helicopter crashed of the coast of Oostende, Belgium while it was hoisting a boat-pilot on board.
A large wave hit the ship and a large amount of the breaking water hit the helicopter and caused a dual flame out.
The pilot succeeded putting the aircraft safely on the water.
All three crewmembers were able to get on board the raft. The boat-pilot drifted of.
Later, a belgian Seaking recovered all 4, who were suffering from hypothermia and took them to a hospital in Brugge.
3 crewmembers suffered from minor back injuries.
I would say job well done for the pilots as I'm sure they did not have a lot of time to respond and I wish them all a speedy recovery.
