a full term in 1944 and re-elected to the following six Congresses, serving until January 3, 1959. At that time, the district consisted of 18 counties in northern California, and only the district in Nevada was physically larger. Thus, Engle used his pilot's license to campaign and meet with constituents. He was dubbed the "flying congressman" and once flew solo to his home in California from the Hybla Valley Airport in Alexandria, Virginia.
