Uplinker,
In your video....that was a Sikorsky S-58T that had the tail rotor drive failure.
The Pilot controlled the aircraft and was maneuvering towards a safe landing area.
He maintained power until he thought he could make an authoritative landing and cut the throttles to Flight Idle.
After the accident I had the opportunity to talk with him about the crash....and he was very bothered that he was unable to land the aircraft safely.
He did his best....but the odds were against him...but he flew the machine all the way to the ground and did not give up trying to land it.
The failure we see in the 169 under discussion was a very different kind and far more critical than that shown in your video.
It was a loss of thrust in the video and just the opposite (apparently) in the 169 crash.
The 58T was a drive shaft failure.....where the 169 was far more complicated a failure.
