This picture is a frame from a prior FPV flight conducted (safely) by the victim.
A 19-year-old model helicopter enthusiast was killed Thursday when a toy helicopter he was flying struck him in the head, a law-enforcement official said.
This is really sad. I cannot fathom being the father standing next to him.
Pilot culture can appear slightly morbid from the outside. We tend to reflect on and rehash accidents more than non-pilots. I think reflections like this are good for safety culture in amateur UAVs too.
I recently constructed carbon/XPS blade-guards for my 20 lb hex... Sometimes during the tedious machining I doubted it was worth the time.
Some may cite the kinetic energy danger in a helicopter rotor vs. multicopters, but the longer you fly, the more likely it is you'll know someone who's had an accident on a multirotor. The more accidents we have, the more we promote the "drones are usually dangerous" misconception. Consider: this WSJ article has a QAV500 FPV video as it's lead media. Concepts distinct to you and I will be conflated by the public.
Let this incident scare you, and be careful.
