The National Air & Space Museum reopened the Boeing Milestones of Flight Hall on Independence Day weekend to mark the museum’s 40th anniversary. The exhibit has been largely unchanged since the museum's opening, July 1, 1976. After a two year renovation funded by a $30 million gift from The Boeing Company, the new installation welcomes exploring visitors to one of Washington, DC’s most popular attractions. Milestones of Flight is located in museum’s main exhibit hall located between the two main entrances.  
Quinn Evans Architects led the design and build-out of the new 19,000-sf exhibit with a new welcome center and several of the most iconic artifacts in the National Air and Space Museum’s collection that exemplify the stories and history of aviation and space flight.  
With the opening of the renovated Milestones of Flight Hall, the Smithsonian Institution looks to provide a transformed and enhanced visitor experience through the introduction of “GO FLIGHT”.

"GO FLIGHT" is “a digital experience designed to allow visitors to make connections with and between artifacts and to share the national collection beyond the walls of the museum. Three components make up the experience — a 16-by-12-foot interactive wall, a mobile app and a redesigned museum website."

In addition to favorites such as the Spirit of St Louis and the famed Bell X-1 rocket that float above visitors, Milestones features a lunar landing module from the Apollo program, SpaceShipOne, and the original model of the Starship Enterprise from “Star Trek”.  
The Smithsonian Institution celebrates the National Air & Space Museum’s forty years through the month of July. The festivities kicked off Friday July 1st with a special evening ceremony and an "All Night at the Museum" celebration to commemorate the date and officially open the newly renovated Boeing Milestones of Flight Hall.
