They're tasty.
I'll even fly a super high altitude mission to an enemy HQ/city for the chance to shoot one down......after asking my country if it's one of ours who's over the enemy HQ.
I just up a fighter with drop tanks, point it that direction, and then work on a car or the house before coming back to find I've either been shot down or I am where I want to be.
Sadly, of the 10 missions I have encountered high buffs, 5 of the buff drivers simply bailed shortly before I made icon range.
