DAYTON, Ohio (AP): The new $40.8 million fourth hangar at the National Museum of the U.S. Air Force has opened its doors in southwest Ohio.

The 224,000-square-foot building near Dayton opened to the public after a ribbon-cutting ceremony Wednesday morning. The building features more than 70 aircraft and aerospace vehicles.

The new building allows the museum to collect pieces from its global reach, presidential, research and development and space galleries in one location.

The hangar also houses the Air Force One used by eight presidents. The plane carried the body of President John F. Kennedy back from Dallas in 1963 after he was assassinated.

The site also has the 96-ton Titan IVB space launch vehicle.
