If Sgt Alvin York could have joined the modern Air Force, he would have flown A-10s!
It makes sense but I have been told that the Air Force has tried to do just this but the Army has refused because they don't want to pay for it out of their budgets because they have their own spending priorities.
And yet we can spend just under a billion to buy a hand full of comparably useless Tucano trainers modified as light attack planes.
