Dear friends of phantom 4 pro, I lost my drone today after a hard fall. After taking off the aircraft lost the control signal and fell in free fall 
Can you still interpret the log below?
This sounds like a likely battery disconnect.
What happened? how to lose control and fall. Does the return home feature not work?
the aircraft disconnected itself, black screen on the iphone 7 with the aircraft information disconnected. I tried to return with rth and did not respond. then fell (I had the impression that it fell accelerating) …

it is very sad that it can happen. auto rth doesn’t work if the aircraft is totally off. maybe this happens because the battery runs out
Were you able to find your Phantom?
Yes, totally destroyed.
