To clarify, what I meant was that the guy who straps into a machine capable of 500+ mph with ordinances and capable of all sorts of aerobatic maneuvers has to accept a certain amount of inherent risk that comes with this operation.    That's what I mean by signed up for.     An Asian mother with two babies at home and her mother in-law sitting in a house didn't sign up for any risk.    Yeah I get it, life sucks for some and ends far too quickly, but it doesn't change the fact that this family didn't sign up for this kind of situation.     I'm not saying pilots are signing up for death when we fly, but we have to accept that this is a risky business we're in.   And lives on the ground matter.
Leave the Vietnam War out of this please.   And also, we're volunteer but we have to sign up for the Selective Service Registration which means males could be called up and then sent off.     Did you also know that I, as a green card holder at 18, had to sign up for the selective service registration as well?    How golden is that.   I can't legally vote for elections but I can be sent off to die in a war.    Anyway I'm a US citizen now but I always found that interesting.
