Re: Accident reasons
IIRC the original anti-crash function refused to go anywhere near the ground if it didn't have good height data on approach. It used a laser altimeter which didn't work in the rain. This made landing in Wales tricky.
The result was that the drone sat there sulking 300ft up until it ran out of fuel and crashed - so the avoid the ground feature was regularly turned off.
