Funny story in Canada years ago:
A 212 with a belly tank is loading at a hot and high pond.
Just about to depart when one donkey quits. Down he goes from a 10 foot hover. Fortunately the water is shallow so he comes to rest upright with water up to the cabin deck.
Our hero wades to shore through water and loon sh#t.
Transport Canada is in the area and proceeds to the scene.
Pilot is in the kitchen of a nearby camp.
Transport Canada: “Captain, when the #2 engine failed did you secure the engine in accordance with the Bell 212 engine failure procedures and checklist?”
Pilot: “ Let me explain one more time! ‘BANG! SPLASH!’ any further questions?

US Army Huey Cobra doing a running landing following a Tail Rotor Failure of some kind.....and it all went wrong shortly after touching down....and as the aircraft was in the process of destroying itself.....Tower called and asked if the Pilot wanted Crash Rescue to respond.
The reply was "How do I know.....I ain't done crashing yet?".

Anybody have a theory what the high pitch whining sound is at 0:15 when things suddenly went pear shaped? They've obviously had a power loss. I wouldn't be surprised if one of the ET drive shaft couplings suddenly let go. I'd like to see the 30 seconds of video after splashdown.

Guy departing from a helipad in the bush.
The area around the pad had been cut during the depths of winter so it is covered with 2-3 foot stumps.
Anyhoo our hero leaps into his Hughes 500D, fires up and departs.
Upon rotation and at a speed of around 10 knots and an altitude of 20 feet Miss Allison throws a hissy fit and quits.
OH flares and does his best but the helicopter impacts with a little forward speed, snags a stump and rolls over.
We fascinated, concerned observers, rush over to the machine.
As we arrive the pilot’s door flips open and OH lifts himself up to the side of the machine.
We look at him…he slowly looks at his watch then looks at us and says: “Yes, it’s still ticking!”
Timex watches..takes a licking and keeps on ticking. Another Timex torture test for the books.
Only injury- one of the guys twisted his ankle on a stump rushing to the wreck.

If the tail rotor had stopped what do you think it would have looked like? Maybe some rotation?
How about when an engine failed and the collective was pulled into the pilots arm pit, the Nr drooped, causing TRRpm to also slow, matching camera shutter speed?
Tail rotor stopped and started... give me strength

Certainly sounds like it might be a broken engine drive coupling screaming away. Effectively an engine failure with both still running.
But then again, having only flown twin engined helis since 1979, I've barely any experience of knowing about this sort of thing compared to the armchair experts here.

Freewheel unit failure? This would explain the runaway engine noise which also appears to remain governed, and not overspeeding and shutting down - and the ensuing sudden drop into the water.

I already pitched that one at #7. Fair bet there has been a near sudden loss of mechanical drive somewhere between the CBOX output and the MGB input and the engine squealed because it wasn't very happy about. Another possibility is a TCU or PT governor issue (it's happened before, sudden loss of engine power due to improper rigging or worn components in both governors or the TCU). Whatever the cause I'm sure they'll work out what went wrong soon enough.
