My favourite anecdote from Airlines for the Rest of Us, a self-published book about U.S. local airlines by Stan Solomon: Ozark Air Lines purchased its first DC-3s from Parks Airlines. To get the planes up in the air as quickly as possible, workers painted out the P and the S from “PARKS” and added “OZ” to the beginning. By accident, one of the planes was painted with the name “OARK AIRLINES.” The management of the fledgling carrier decided to leave it as it was for several months to prove to the public that the airline owned more than one airplane.
