Then, stop fear-mongering.
Stop focusing on Pirker's airplane. Stop focusing on Pirker's actual flight. Pirker's flight is irrelevant. Pay attention instead to what this means for the rest of us.
Presenting facts based on years of medical experience to counter your ******** statements that foam will only leave a bruise is not fear mongering. It is reality.
This has little to do with Pirker's flight, but everything to do with safetly when we fly.
I don't care if you are flying a Phantom or a gas powered fixed wing - you need to KNOW what your bird is capable of IF it should ever hit someone in a crowd. You will be liable.
And if you think that foam will only leave a bruise, I don't want you flying. It tells me you have no concept of safety, and absolutely no idea of what your rig is capable of, which further tells me that your own ignorance may lead you to fly dangerously.
I've never advocated that flying should be limited to AMA club flying fields. But I will advocate for common sense and safety when flying in public, and so far several people here have demonstrated a lack of both.
If you continue to fly under the impression that your bird couldn't harm someone, then you are a threat the hobby and all of us who participate in it.
I think it is quite idiotic to view that as fear mongering.
