lol. The way you worded that, you can't help yourself, can you? Gimme a kiss!
Agreed with everything you said except the tail separation in the bolded part of your quote.
You're saying the helo hit the mountain a first time, then the tail section blew off causing the helo to lose its counter-rotation torque and as a result, the helicopter spun around and then crashed a 2nd and final time?
If that's what you meant, then you're basically saying the loss of the tail section (with tail rotor) caused the accident. That means it hit the mountain twice but there is no sign of that at all. As a matter of fact, it shows the opposite with the location of the tail section, right at the front of the crash area. If your scenario is correct, the tail section would've been at a separate location, and we would've seen a secondary impact area and there was no such thing.
The fact that the tail section is right at the impact area indicates it came off at that spot.
To me, looking at the pattern of the charred, impacted ground and the location of the tail boom suggests that the pilot suddenly realized he was way too low (for whatever reason, that's the 2nd part to figure out), tried ascending fast but ran out of space, altitude & time as the mountain came up on him too fast. Nose-belly slammed into the terrain and because it was at an incline and the impact was hard of course (you can see that in the video of the first responders the helo was seriously busted up) the front end basically dug into the ground and the helo quite possibly flipped over forward and slammed into the ground and exploded and that's what caused the tail section to shear off and land forward of the impact area.
The 2nd part is why was he flying so low in the first place knowing the terrain was very dangerous with high mountain peaks everywhere. That's really the main question since we know from the testimony given by the comms guys that he had ordered the other two helicopters to increase altitude and they did. But why was he too late in doing so? And why wasn't he at a higher altitude in the first place? Too much fog & cloud cover and he wanted to fly under it for more visibility? All these things point at very unfortunate pilot error and nothing to suggest foul play.
