Fairchild-Maxson Mark I Line of Position Computer

This 1938 mechanical computer was a remarkable attempt to automate complex navigational processes. Instead of spending minutes making manual calculations, navigators could simply input sextant observations and accurate time readings. It was too expensive and heavy for regular use. Only several dozen were made for the Air Corps and Navy.
