Header strip identifying this as Figure 1 from FBI case file DB Cooper-3169, dated 12/4/71, from the Portland sectional aeronautical chart.
Portland-area aeronautical sectional chart (likely Portland Sectional) with a flight path overlay drawn from north to south, passing through the Oregon-Washington border region. Waypoints are marked with letters H, G, D, E, J, and A along the route. The flight path appears to trace the suspected trajectory of Northwest Orient Flight 305 (the D.B. Cooper hijacking) heading southward from Seattle through the Portland area. Airspace altitude annotations include 6500 MSL, 4500 MSL, and 8500 MSL. Multiple terrain elevation markers, airports, towns, and navigational aids are shown across the Columbia County, Portland, and Clackamas County areas of Oregon and Clark County, Washington.
Scanned aeronautical sectional chart with moderate resolution Some small text and elevation numbers are partially legible Flight path overlay lines are clearly visible Waypoint letters (D, E, J, A, H, G) are legible Peripheral and fine-print map details are difficult to read
