context_page_description: The 91st Cyberspace Operations Squadron is an active United States Air Force unit, currently assigned to the 67th Cyberspace Wing at Kelly Annex, part of Lackland Air Force Base, Texas.
  The 91st delivers cyber warfare capabilities to combatant commanders. It provides the Air Force with manpower.
context_section_description: U.S. civilian and military leaders were concerned with Nazi Germany's preoccupation with South and Central America. In order to prepare for possible hostilities in our own backyard, the military planners needed accurate charts and maps of all of these regions. Millions of square miles were virtually unexplored and uncharted. The 91st was given the tremendous task of getting this job done through aerial photography.
  Elements of the 91st Photographic Mapping Squadron were deployed to the Antilles Air Command in April 1943 until June 1945. Flight "B" of the 91st flew throughout South and Central America and the Caribbean. Staging from Borinquen Field, Puerto Rico, aircraft and crews were deployed throughout the area.
  Aircraft of Flight "B" saw extensive flight activity over and around such places as Talara, Peru (between 1943 and 1944), Atkinson Field, British Guiana (1944–1945), Recife, Brazil (1944–1945), Howard Field and Albrook Field, Canal Zone (1944–1945) and Natal, Brazil (1945). These operations, mainly aerial mapping, also included intelligence work, providing the United States with a storehouse of cartographic data on these regions that is still in use today.
  The 91st was formally attached to the 311th Photographic Wing (later known as the 311th Reconnaissance Wing), and Flight "B" was available to the Sixth Air Force's commander for other duties. The unit flew a variety of North American F-10 "Mitchells" (the photo recon variant of the B-25D) as well as several Boeing F-9s (photo version of the B-17).
  Flight "B" was seemingly "everywhere" in the Caribbean region during the war. After the war ended, the squadron was based at MacDill Field, Florida, and later with the 24th Composite Wing at Howard Field, Panama, carrying out photo-mapping and charting missions in Central and South America. The squadron was assigned to the new Strategic Air Command in 1949 and moved to McGuire Air Force Base, New Jersey where it engaged in long-distance photo mapping as part of SAC's global strategic reconnaissance mission.
