It seems that Hawthorne Nevada Airlines was only so named in 1968 and early 1969. Earlier it was Mineral County Airlines. Hawthorne is a small town but a casino on Walker Lake drew gamblers from California. N15570 fatally crashed into Mount Whitney on 18 February 1969. Our other photo of N33639 suggests the airline was renamed Air Nevada immediately thereafter. The DC-3A was originally NC28305 of Pan Am. Photo from: San Diego Air & Space Museum
