A hand-annotated military topographic map from the "Misty" Fast FAC program, showing the Laos/South Vietnam border along the Ho Chi Minh Trail. Misty pilots flying high-speed, low-altitude reconnaissance in F-100F Super Sabres marked reference "Delta points" like these to relay enemy truck park and target locations to strike aircraft, playing a critical and dangerous role in the interdiction campaign against North Vietnamese supply lines.
