Truly horrific accident. Helicopter with two engines, great ability to glide, very strange. Lord rest all the poor victims of this awful event.
True Dick. I would guess either catastrophic rotor failure or maybe a pilot heart attack. I'm sure they will discover the cause in time. How unlucky for all concerned that it came down on the flat roof of a pub on a busy Friday night.Just read in the paper, they "grounded" the same type 'copter last year for cracks in the rotor blades. Makes you wonder? ???
