Description
This envelope, dated April 15, 1930 depicts a fascinating map from the Army Air Corps Maneuvers held at Mather Field, California, from April 1 through 25, 1930. The battle simulation map shows Northern California, with portions of the land labeled as "Held By 'Enemy' Troops" and "Enemy Fleet" along the coastline. This event was then the largest aerial maneuvers held in the western United States, involving 135 U.S. Army planes from across the country. According to the Appeal-Democrat of Marysville, California, a purpose of the event was to "quiet the fears of some regarding possible dangers of aviation." A significant achievement of this event took place on April 12, as 19 pilots of the 95th Pursuit Squadron, led by Capt. Hugh Elmendorf, set an unofficial world record for altitude formation flying over Mather Field, Calif. The P-12 pilots reached 30,000 feet, shattering the old record of 17,000 feet.
