It seems unlikely to me that the pilot would have accidentally disabled the autopilot and not noticed, even if he was distracted talking to the passengers or plotting a course, but could a passenger have done it? What would it take on that helicopter with these avionics, is it even possible to do accidentally?
To be very clear, I am assuming:
- a passenger was up front
- autopilot was active
- the passenger used a control
There is no evidence that any of these happened, and there are plenty of alternate explanations.
With each passing day, the speculation and theories become ever wilder.
