the 12-month ending December 31, 2019, the airport had 75,647 aircraft operations, an average of 207 per day: 98.5% general aviation, <1% air taxi and 1.4% military. There are 291 aircraft based at this airport: 85% single-engine, 13% multi-engine, 1% helicopters, <1% ultralight, and <1% jet aircraft. The airport also hosts an armory belonging to the Colorado Army National Guard. HHC, 5th Battalion, 19th Special Forces Group is based there. There are no military aircraft based at the airport. Spaceport proposal In October 2011, the Governor of Colorado, John Hickenlooper, formally requested that the federal government designate Colorado a "spaceport state" and that the airport be designated a spaceport for suborbital horizontal takeoff flights (HTVL and HTHL). Spaceport designation would allow a facility offering suborbital tourism, travel, and cargo transport from one point to another on Earth. The Denver Post reported that "No vertical launches are planned at the Front Range, unlike most of the other eight certified U.S. spaceports. Instead, space planes — an emerging technology — will use regular runways and jet engines to take off and land, switching to rocket power above 50,000 feet." Media sources have suggested that the Sierra Nevada Dream Chaser spaceplane may be used for suborbital spaceflights and that Colorado Air and Space Port may prove to be the preferred location, over Spaceport America in New Mexico. , news reports indicate that the Colorado Air and Space Port proposal is gaining traction with political interests at the state and federal levels as well as with industry participants. One of those commercial interests was XCOR Aerospace, which was considering Spaceport Colorado as a candidate for HTHL operations with their Lynx rocketplane. However, XCOR announced in July 2012 that they would be moving their company headquarters and research and development activities to Texas, in part due to a significant set of financial incentives () offered to XCOR by the Midland Development Corporation (MDC) and the Midland City Council. , Colorado state law "grants limited liability to spaceflight companies, allowing spaceflight participants who sign waiver forms to sue only if they are injured or killed as a result of a firm’s 'willful or wanton disregard' for safety." Spanish architect Luis Vidal produced an architectural concept for the new airport in 2013. In December 2017, British aerospace company Reaction Engines began construction of a test facility at Colorado Air and Space Port for the development of its
