A U.S. Air Force Douglas C-133 Cargomaster sits on the ramp during the Military Air Transport Service (MATS) era of the early-to-mid 1960s. One of the largest cargo aircraft of its time, the C-133 hauled oversized loads—including Minuteman ICBMs and heavy equipment—between the continental United States and overseas bases, playing a vital logistics role during the buildup of American forces in Southeast Asia.
