Random Crash - What happened?

Order of events:
1. There is a little bit of jello in the video.
2. OSD suddenly froze and became unresponsive.
4. Drone seems to disarm and falls out of the sky inverted.
5. Drone crashes into rocks and ejects the GPS module (wires can be seen hanging).
6. Drone crashes and the video is temporarily lost for about 5-10 seconds but the recording continues.
Facts:
Throughout this whole sequence of events signal and telemetry were not lost. The video kept recording for several minutes until I stopped it to prevent the O3 AU from overheating.
Damage:
1. GPS was ejected during the crash and went missing.
2. O3 AU Antenna was badly damaged beyond repair.
What could possibly cause something like this?

Could be something shorting out while you were diving.
Maybe some loose solder flying around or some wires/metal touched where it should'nt.
Hard to guess :/

Sorry about the crash. Usually cause for this type of crash is either loss of one propeller, loss of motor ESC, or fault in flight control mode.

[@DZARO]

Yeah, but guess what: I unplugged the battery, bent back the prop, plugged the battery back in and it armed and flew fine. WHAT THE ACTUAL F*** HAPPEND ONLY LORD KNOWS!

[@Tonynux]

Did you understand why?

[@DZARO]

Nope, I have no idea. It was not a disarm, I have no idea what it was. When I re-plugged the battery at home, everything was working fine.

ESC dsync?

[@DZARO]

@@arpan.sarkar Yeah, but the OSD froze and then went away as well so that might not be the cause.
