The red outline centered on this aerial photo map shows the CAP 2-7-4 area of operations through 1970 and 1971. The the left-hand diagonal obscures QL-1 (Highway 1). The Song Thanh Quit bridge is just above the red number 5 in the lower middle of this image. This map may look a little lopsided because the right edge is uneven.
