    Air pollution by jet aircraft at Seattle-Tacoma Airport

    This 1970 U.S. Weather Bureau technical memorandum by Wallace R. Donaldson examines air pollution caused by jet aircraft operations at Seattle-Tacoma Airport. The report, published by the Environmental Science Services Administration's Western Region office, investigates the environmental impact of jet exhaust and emissions in the airport's vicinity. It serves as an early government study linking aircraft activity to local air quality concerns in the Seattle-Tacoma area.

    Sea-Tac Airport Aerial View, 1961

    Black-and-white aerial photograph showing a commercial airport with a central terminal building, circular access road, parking areas, multiple runways in an X/cross configuration, and what appear to be propeller-era aircraft on the apron. The layout and scale are consistent with a regional hub airport, likely dating from the 1950s or early 1960s based on aircraft types and terminal design visible, but no text, captions, or watermarks are present to confirm the specific facility or date.
