ASA was started as Merrell Aviation Ground School by Creighton Merrell in 1940. The company’s primary goal soon became the training of post-war military pilots returning from active duty to work in the early civilian airlines. Plotters, regulations and training manuals were the first products. In 1960, the company broadened its production and development efforts with additional pilot supplies and books added to the ground school training line.
