Briefing notebook spreads for 7, 11 and 19 January 1970 kept by Captain Vaughn Bobby Ross, a UH-1 pilot supporting MACV-SOG reconnaissance operations. Alongside the daily survival letters, frequencies, teams on the ground and Covey forward air controller assignments, the 11 January page records a Bright Light changeover, the standing mission to recover downed aircrew or missing team members. The facing page shows the other half of an aviator's life: aircraft tail numbers with maintenance squawks, and reminders about the unit fund, the water tank, spare parts and officer efficiency reports.
