This museum in a historic hangar on what was once Lowry Air Force Base (and is now the upscale Lowry development) keeps getting better and better. At one time a fairly standard air and space museum, it now boasts an impressive collection of rare aircraft (from a B-1A Lancer to a RF-84K Thunderflash Parasite), a cutting-edge flight simulator, and even an X-wing that was a prop in “Star Wars”—thanks to a local fan club of the movie that is in possession of this piece of sci-fi lore. The best days to visit are the cockpit demo days on the second Saturday of each month. Allow 1 hour.
