This navigation reference page from the 366th Tactical Fighter Wing's 1971 'DaNang Inflight Aid' manual lists TACAN radio beacon stations across the Southeast Asia combat theater, essential aids that allowed F-4 Phantom crews to navigate accurately between bases in South Vietnam, Thailand, and Laos. Handwritten additions in the margins, including arming area coordinates and additional station data, illustrate how aircrews kept their manuals updated in real time as the operational picture changed.
