The message here is: Don't annoy fisherman trying to have a pleasant afternoon with your flying gizmos.
Tice Ledbetter was flying his drone over the pier at Pacific Beach, San Diego when he got a little too close to a group of men fishing.
After noticing their airborne spectator, one of the men cast his line and hooked the drone in one spectacular, long distance shot. Although he didn't seem able to reel it in, footage from after the encounter shows a length of fishing line being unwound from what appears to be a quadcopter.
Here's a video of what the drone was trying to film before it got snagged.
