Has anyone looked at the Pilot defensive handgun training program? I think you see a good idea what training it takes to have a sane fighting chance.
BTW it’s a 6 day really intense course.
If there were two airliners going my way identical in every way except one had an armed pilot, I’d likely take that plane. It is certainly not at all negative in my mind. It’s a good example of professionals taking on another set of skill that lives depend on.
