6. even though the response of the machine is identical to what would happen if the the tail fell off.
1. No. This is clearly loss of TR drive, not TR control.
2. Yes.
3. No (unless the TR drive output on the MGB failed).
4. No.
5. No. He's lowered the collective in response to the failure (you can see the rate of rotation decreasing slightly as it descends).
6. You're saying that if the tail fell off, with all that weight suddenly missing so far from the CofG, it would respond identically to if the tail just lost drive but didn't fall off?
