    U-2 Navigation

    Alex look on pages 4-28 and 4-29 of the manual and you will find references to "precomp" sheet.

    All of the missions were to follow specific ground tracks at specific times to have the shadows on the ground correct for the photo interpreters, so all of the sextant work would have been precomputed prior to the flight.
