USAAF Radio Data and Flight Information TO 08-15-2
This is an original WWII-era US Army Air Force technical order for Radio Data and Flight Information. The 40-page document provides various data for the use of pilots and radio operators while in flight across the US.
USAAF pilots and radio operators used this data while flying in the US while in training, conducting transport flights, or ferrying aircraft.
It is in good condition given its age.
