We *may* have a smoking gun in one case of "falling out of the sky" in a case reported by Daryl Watkins.
In that case it appears there was an erroneous detection of "motors obstructed" error that resulted in the invocation of a ESC FW "safety" feature introduced in recent firmware where the Inspire will shut off its motors if it thinks it detects an obstruction with the motors.
This feature was added in the firmware release after Myth Busters show premiered that showed the dangerous effects of drone propellor contact with the human body.
I myself have witnessed the "motor obstructed" error, even while the aircraft was sitting in the ground before motors were even armed.
I think we may have ourselves a case of erroneous "motor obstructed" errors causing Inspires to shut off their motors and fall from the sky.
More to come and we need more DAT log files from fallen Inspires but at least in throne case there was no power outage, just the "motor obstructed" error 1 second before the Inspire began tumbling from the sky, all the while being powered and transmitting its telemetry.
Note that in at least this case the aircraft remained powered as the telemetry continues to come in that the gimbal angle exceeds max etc.
In other reported "fall from the sky" cases the aircraft apparently looses all power (hinting at a possible separate issue(s) related to the battery shutting down.
