I visited the National Air and Space Museum’s lesser-known second location. One display stopped me in my tracks.

• I visited the National Air and Space Museum’s second location, the Steven F. Udvar-Hazy Center.
• The Virginia museum has over 200 aircraft and spacecraft in 340,000 square feet of exhibit space.
• The space hangar featuring the space shuttle Discovery was a highlight of my visit.

The National Air and Space Museum’s flagship location in Washington, DC, is one of the most-visited museums in the US, but the building isn’t large enough to display all of the aircraft and spacecraft in its collection.

That’s where the Steven F. Udvar-Hazy Center comes in. The National Air and Space Museum’s lesser-known second location, a hangar-like structure in Chantilly, Virginia, offers 340,000 square feet of exhibit space with over 200 aircraft and spacecraft on display.

“What you’re going to see are the first, the last, the only, the last remaining, the most significant. So it’s an A-plus, as far as the collection,” Holly Williamson, the museum’s public affairs specialist, told Business Insider.

I visited the Udvar-Hazy Center in January 2026. Here are the coolest things I saw.

The Steven F. Udvar-Hazy Center in Chantilly, Virginia, is located on the property of Washington Dulles Airport.

Unlike at the National Air and Space Museum’s flagship DC location, where timed-entry tickets help manage large crowds in the smaller space, reservations are not required at the Udvar-Hazy Center.

Admission to the museum, which is about 25 miles from DC, is free, and parking costs $15.

The museum takes advantage of its proximity to the airport with the Donald D. Engen Observation Tower.

Inside the tower, I watched planes take off and land at Washington Dulles International Airport while listening to live ATC audio.

The Mary Baker Engen Restoration Hangar gives a behind-the-scenes look at how the museum restores historic aircraft.

Among the works in progress when I visited were “Flak-Bait,” a Martin B-26 Marauder that flew 202 combat missions during World War II and participated in D-Day, as well as a Sikorsky JRS-1 seaplane that was at Pearl Harbor when it was attacked on December 7, 1941.

The B-29 bomber Enola Gay, which dropped the atomic bomb on Hiroshima during World War II, is in the museum’s collection.

The “Little Boy” atomic bomb weighed 9,700 pounds, forcing the aircraft to remove most of its protective and defensive armament in order to carry the enormous weight.

The Enola Gay exhibit sparked controversy when the plane was first displayed in 1995, as veterans’ groups and anti-war activists debated how the historical narrative around the use of the atomic bomb should be presented.

The Boeing 367-80 Jet Transport, the only model of its kind ever built, was the prototype that led to the development of the Boeing 707 jetliner.

Boeing began building this prototype jet in 1952, and it flew for the first time two years later. It traveled 100 miles per hour faster than the de Havilland Comet, the world’s first jetliner developed in the UK, and had a range of over 3,500 miles, revolutionizing air travel.

The museum also featured a Concorde supersonic commercial jet that was operated by Air France.

Traveling at twice the speed of sound allowed the planes to cross the ocean in record time. Concorde’s fastest flight from New York City to London lasted just 2 hours, 52 minutes, and 59 seconds.

The museum’s Concorde jet, which flew for Air France, measures 202 feet and 3 inches long with a wingspan of 83 feet and 10 inches.

Other retired Concordes can be found at museums in New York City, Seattle, Paris, and England, among others.

One of the museum’s centerpieces is a Lockheed SR-71A Blackbird, the world’s fastest aircraft propelled by air-breathing engines.

The Lockheed SR-71A, a supersonic reconnaissance aircraft, was designed to fly high and fast enough to avoid Russian missiles during the Cold War. It was capable of flying at an altitude of over 85,000 feet and at speeds exceeding three times the speed of sound, or about 0.7 miles per second.

The aircraft became known as “Blackbird” for its black paint, which was designed to absorb radar signals.

This Blackbird logged 2,801.1 hours of flight time over 24 years of service before retiring in 1990.

The entrance to the James S. McDonnell Space Hangar, with the space shuttle Discovery placed front and center, stopped me in my tracks.

It’s hard to capture the full scale of Discovery in a photo, but I found it awe-inspiring to see such an enormous, historically significant spacecraft in person.

The shuttle measures 122 feet long, 78 feet wide, and 57 feet tall, towering over the other artifacts in the hangar. When fully loaded for missions, the orbiter weighed around 250,000 pounds.

Discovery was NASA’s longest-serving orbiter and flew 39 missions.

Among its many historic accomplishments, Discovery deployed the Hubble Space Telescope in 1990 and became the first space shuttle to dock with the International Space Station in 1999.

Hanging above Discovery was the jet-powered backpack astronaut Bruce McCandless used during the first untethered spacewalk in 1984.

The Manned Maneuvering Unit was a backpack propulsion device powered by nitrogen jets that allowed McCandless to fly around 300 feet away from the space shuttle Challenger.

His untethered spacewalk was immortalized in an iconic photo of the lone astronaut floating above the Earth.

The Udvar-Hazy Center is worth the detour from the National Mall.

My phone’s step counter recorded nearly 10,000 steps on the day I visited the museum. There’s an incredible amount of ground to cover and objects to see.

I can’t believe I didn’t know that the National Air and Space Museum had a second location when I started planning my visit to Washington, DC. Now, I’m recommending it to all of the air and space enthusiasts I know.
