Agile, that's what you should do but it's not recovering to visual flight ie land before you have to exercise your instrument skills. Winemaker, read the following thread for discussion on a similar accident. Once in the predicament extraction will be dependent on your instrument flying skills (if you have any and if the aircraft is so equipt), nature of the weather and nature of terrain.

Thanks for that. I was wondering if there was a maneuver like a box canyon turn that might be done ASAP when entering cloud to escape.

That the aircraft ended up in the state it did due to mismanagement is quite a reasonable thing to speculate. Plenty of R44 accidents follow a wearisome pattern of running out of power or overpitching whilst doing something - like a wedding job or a photo job - which involved lots of traps for the unwary. And it is very easy to run out of power 4 up in an R44 if you start making steep approaches/downwind approaches/low airspeed approaches. Plenty of the time folk fly them 2 up and have oodles of power in reserve. Then they add a pax or two and a few items in the seats and more than half a tank of fuel and.. hey presto: accident waiting to happen.

I’d bet the farm on user error.

might take you up on that bet.

Reports that the pilot isn't medically fit enough yet to be interviewed by investigators. Her injuries must be pretty serious that she has not said anything yet.

The crash site appears to be a golf course, which should leave plenty of options for an approach or engine out event.
It should not be necessary to end up with an impact like that with all that open land around.

The departure point was the same golf course. The helicopter crashed shortly after take-off and was witnessed by people playing golf.

How it can happen, starts at 00:47

At around 6'30" to 6'40" what sounds like a 'beat' is audible. ie a low frequency due to the interaction of 2 high frequencies. Is it possible that this is due to sound bouncing back from the ground? If so, is that a 'thing' and can it ever convey useful information?

sounds like blade slap to me, due to loading the rotor (pulling g) as the pilot starts to lose control.

That you are about to die, possibly.
