We have a new article at SimHQ...a series of pictures from a WW2 RAF A2A gunnery training pamphlet. Take a look! See how gunnery was taught way back when!
http://www.simhq.com/simhq3/sims/air_combat/RAFgun/ If the pictures come out small, use a graphics editor to blow them up. I'm trying to redo these in .bmp format to see if they are more easily read...try these first...then check back in a day or so for the new pics.
