The other I don't know the cause of but it appears that it "struck the water" , maybe engine failure but unlikely if you have enough energy to 'strike the water' (and damage the helicopter so badly) then you probably have enough energy to flare and land gently. Was the second one and engine fail? Anyone know yet?
Muddled thinking, only in your mind. My thinking is clear.
There are multiple reasons it may have "struck the water" and I agree that engine failure is not necessarily the most likely scenario. Same operator, 2 in 2 days, not good. Even the "successful" ditching is a problem, now you have people floating in a raft requiring rescue, way outside most OGP company risk profiles.
It may have been a mechanical failure, surely unlikely in such an unstressed machine with only one engine? It may have been crew error?
But, had it have been an IFR twin, it would have probably been operated in such a way that contact with the water would be minimized.
