I'd guess the odds of successfully deploying a knife mid-crash are fairly slim, at least without hours of real-life practice training.

I'm sure the temperature of the water didn't help either.
1) you have five people who likely have never been in a helicopter before.
2) they are tied into the aircraft with a complex harness (which in general is a good thing).
3) They only received scant training about what to do in case the helicopter goes down.
4) as the helicopter does go down the people start to panic. There is no buddy system established so that the passengers can help each other get out of the aircraft
5) any of the scant training goes out of mind as the helicopter does go down.
6) for reasons unknown the Pontoon system does not work and the top heavy helicopter at this point tips over.
7) as the helicopter flips over and the current starts pushing the sinking wreck along as complete panic compounded by total spatial disorientation ((what you expect to be up is now down and the aircraft is filling with dark cold water) takes over the people in the passenger compartment.
I have done professional shoots out of a helicopter several times , with the doors off and never with more than three people in the passenger compartment and those were in either in a civilian version of the UH-1 "Huey", Long Ranger, or Jet Ranger helicopters.
Even a fellow professional photographer friend of mine who has gone through HUET (Helicopter Underwater Escape Training
https://en.m.wikipedia.org/wiki/Helicopter_Underwater_Escape_Training) course twice (he does a lot of work photographing offshore oil rigs) thinks that he would not have survived this crash given the circumstances.
