Will SW use magnetic north for compasses?

One of my customers was a navigator on a B25 during and after WWII in the pacific. He speaks often of navigating by the stars when he could, mostly to verify his position that he had already figured out by other means. He was very glad to have this tool on long ferry trips with bomb bay tanks from Japan to Hawaii. "Midway is a very small target in a very big ocean when your tanks are running dry and there ain't no place else to go"
