In 1928 the Pikes Peak Flying school began at the airport, and was sold by Henry Chase Stone the following year. In 1929, Pikes Peak Air Commerce, Inc. operated what Ralph N. Miller described as "possibly the highest flying school in America today" at Alexander Airport. Planes flying in and out of the airport at in altitude, Miller stated, were 80% as efficient as planes and have harder landings than planes operating at sea level because of the thinner mountain air. This can make for a more careful, conservative pilot.
