The Howard Cannon Museum at Las Vegas McCarran Airport is located just above baggage claim. It is as far as I know the most extensive collection of aviation memorabilia in the terminal of a major airport with the exception of the Museum at San Francisco. This free museum is named after Nevada Senator Howard Cannon, who was an instrumental figure in deregulation of the airline industry in 1978. It is open 7 days a week 24/7 and is free to the public.
