I certainly know more people who were killed in road accidents than flying, and that's pretty much what one would expect isn't it?
I don't know if it is. I'm not a statistician but the pool of flyers that you know will be a lot smaller than the pool of drivers and being as flying is intrinsically more dangerous than driving (I'm talking about GA flying) if you take deaths per participant then I guess in theory you should know more dead pilots. I certainly do. I could be totally wrong in my assumptions though.
The interesting question would be how many pilots are killed in car crashes.
