I'd suggest patience to all.
I don't see why speed of investigation should depend on the question if it is a Helicopter in development or in operational use.
It rather depends on the complexity of the task on hand. And this is obviously more complicated for a new model especially when it crashed during expansion of the envelope. The difficult task in that case is to find out whether it was due to a mechanical malfunction an unanticipated effect (aerodynamic, aero-elastic, etc.) or something in the interaction man -machine while in yet unproven terrain. On the plus side they might have more data due to instrumentation and chase aircraft.
For Bell finding the real cause will indeed be urgent because it will be important for the future of this type.
