Problem: Although used in the Census and the American Community Survey, "Some other race" is not an official race, and the Bureau considered eliminating it prior to the 2000 Census.

Problem: The Air Commerce Act of May 20, 1926, is the cornerstone of the federal government's regulation of civil aviation. This landmark legislation was passed at the urging of the aviation industry, whose leaders believed the airplane could not reach its full commercial potential without federal action to improve and maintain safety standards. The Act charged the Secretary of Commerce with fostering air commerce, issuing and enforcing air traffic rules, licensing pilots, certifying aircraft, establishing airways, and operating and maintaining aids to air navigation. The newly created Aeronautics Branch, operating under the Department of Commerce assumed primary responsibility for aviation oversight.
