Not a crash. That “drone” auto-landed due to low battery. It has a very short loiter time, maybe 15 minutes, so it is of limited usefulness for real time monitoring of anything. That one prop is fouled shows it was making power when it contacted the brush.
One item not mentioned in the story: The lat/long of the launch site is still in the memory of the on board electronics, and can be accessed and read. The flight path is also recorded as well as pics or video.
Wrench - how long can one of those things stay aloft?
Thanks for that info.
