I know some here have poo-pooed the idea that the crew fatalities were caused by a secondary drop. Please tell me where my logic is wrong:
Rotor blades appear reasonably intact - strongly suggesting they were stationary or at least only moving slowly when the heli went through the roof.
Multiple bar patrons report a two-stage collapse of the ceiling, with some duration of pause between the initial impact and the total collapse.
Members here have stated that if "it dropped like a rock" with the blades not turning, then the multi-ton craft would have smashed through the fairly weak roof on initial impact.
Also stated by members - an auto-rotation or semi-controlled landing "soft" enough not to immediately collapse the roof probably would not have resulted in fatalities.
So - is it not possible that the pilot and police officers "landed," halted the blades and possibly removed their seatbelts/harnesses in preparation to get out of the craft, and that's when the roof gave way?
