Urchin, if in AH we always had 17 wingies in box formation in B17's, and a squad for escort, we would fly at hell 10k even!!
A lone buff in ww2 was dead meat, a lone fighter was too if it couldn't run.
A lone buff in AH is dead meat at anything less than 20k if attacked by someone who knows what they are doing.
I plucked 2 17's outta the sky who were at 10-12k, flying close to each other, with some scort, in 2 passes.
