Lol.  Title is funny.  It looked like the party stopped when the multi-copter went down. Who knows what happened.  It looked like it was flying pretty well.   It's the unexplained drops from the sky that make flying risky.   I worry more about that then actually crashing into objects.   Prop break, depleted battery, radio interference, kill switch (CSC) who knows.
update:  I found out that the craft ended up in a river just out of sight of the camera.   It looked like an Octo.  I'm not sure what flight system.
