There is a very good video of an R44 down under that gets into all sorts of trouble due to poor management which was attributed to LTE, but isn't really. From a dozy lack of awareness that the aircraft was running out of power, to pretty much losing control took less than 10 seconds. And under stress, the pilot fought the aircraft almost into the sea, before it flew itself out of what had become vortex ring state. The one thing the pilot didn't do was lower the collective, roll on and get airspeed. Lucky. Very, very lucky.
I can't upload my versions of it. But maybe someone has another format (I have non-accepted MPEG & FLV).
