...system uses a blank globe and four drawing instruments to locate positions graphically. The navigator must "shoot the angle" of two stars with a sextant. He marks on his globe the exact substellar spots of these two stars (i.e., the spots where these stars are directly overhead-obtained from star tables).

At high speeds and at mind-fogging altitudes the quickness of the method may be literally...
