On July 15, 1916, William E. Boeing (1881-1956) incorporates the Pacific Aero-Products Co. in anticipation of a U.S. Navy contract for training aircraft. Although the navy rejects his original aircraft, Boeing will keep trying and win a contract for a new design after the U.S. enters World War I.
After the navy rejected his original design, the B&W, Boeing persevered. Soon after the U.S. entered World War I on April 6, 1917, he secured a contract for a new design, the Model C naval trainer. Pacific Aero-Products was reincorporated as the Boeing Airplane Co. the following month.
