I have to say....when I think of someone like Terry Pratchett who is fighting for his life and would literally give anything to NOT have his mind work in the manner described above, it kind of makes me want to puke when I read that posting.

I don't believe the assumption is that because pilots are skilled at their profession that they will have James Bond's shooting skills.....I believe the assumption is the pilot is better able to defend himself (thus the lives of those under his professional care)if he has a weapon.
Such an accidental discharge is extremely unfortunate and frightening.....but the simple truth is that gun will beat box-cutter pretty much every time.
