many private pilots end up killing multiple members of their family
They sure do. The family flying vacation that is so important they are not going to let a little bit of weather get in their way.
My cousin - pilot - and his three passengers were all killed. He flew into one of those podunk fields with no local control to refuel. On takeoff some idiot flew right across their nose and there was nowhere to go but down. My cousin was 60. He loved flying.
