Falcon 900?
Sir, (with respect) Is it fair to say that you have never flown this (or any other) helicopter?
If this accident was caused by fuel exhaustion (or starvation) the very fine pilot at the controls (and he really was a top guy) would have auto-rotated, taking extreme care to monitor and maintain MR speed.. even faced with the usual inner-city low-level difficulties.
How then would you explain the (alleged) stationary MR blades on the accident aircraft?
Cheers, TP
