Charles Lindbergh's solo trans-Atlantic flight. Lindbergh was made a member of the Quiet Birdmen. Unusually, a former combat foe was invited to join the club: Ernst Udet, the highest-scoring German flying ace to survive World War I. Known as a fun-loving playboy, Udet performed aerobatics at the National Air Races in Cleveland in 1931 and '32, Los Angeles in '33, and again in Cleveland in '38. While visiting the U.S., Udet befriended Lindbergh, Eddie Rickenbacker, Jimmy Doolittle, Wiley Post, Roscoe Turner and other American QBs. Outside of New York, other Quiet Birdmen regional groups, or hangars, were formed. Before 1938, the club had a strict agreement against having a constitution, by-laws, dues, assessments, or club officers. No business was to be conducted, and no sales. Only male aviators were allowed to join, not female aviators or "Keewees" (non-flyers). At the Cleveland Air Races in 1938, the QBs adopted a slightly more formal arrangement: a Board of Governors would be composed of one member from each hangar, and this board would choose an Executive Committee. Each regional hangar was to select a Key Man to handle club business. A year later, the group settled upon a QB Code of Procedure which described the structure of the club. During World War II in London, England, a temporary hangar was formed in 1943 for club members posted to the UK. The club's national Code of Procedure was modified again in 1953. In addition to the still existing New York Hangar, other early Hangars, originally called "leantos" to the original New York Hangar, had been formed. Currently Hangars are formed independently and exist in Washington DC, Cleveland, Atlantic City, Wayne, San Francisco Bay Area, Los Angeles, Palomar in San Diego County, Oxnard/Santa Barbara, Fresno, Santa Ana, Long Beach, Palm Desert, Philadelphia, Rhode Island, Ocala, Seattle, North Cascade in northern Washington state, Milwaukee, Fort Worth, Amarillo, Dallas, Houston, Phoenix, Columbia, Hilton Head and Greenville in South Carolina, Daytona Beach, Honolulu, Kalamazoo, Lansing, Boise, Hartford, Rockford, Akron, Indiana, Syracuse, Las Vegas, Cincinnati, Tampa Bay, Orlando, Melbourne, Venice, Stuart, Jackson, Knoxville, Wilmington, Greensboro, New Orleans, Cape Cod, Kansas City, Austin, Dallas, San Antonio, Buffalo, Rochester, Binghamton, Fort Smith, Chicago, Jackson Hole, Boston, Somerville, Hilton Head, Anchorage, Hagerstown, Denver, Lehigh Valley, Pennsylvania, Atlanta, Waterloo, and Tulsa, Shreveport, Colorado Springs, Salt Lake City, Pensacola, Trenton, Bangor, Portland and perhaps other cities throughout the US.
