This is the oldest known type of jet pack or rocket pack.
One Bell Rocket Belt is on display at the Smithsonian Institution's National Air and Space Museum annex, the Steven F. Udvar-Hazy Center, located near Dulles Airport. 
The Air Force Space & Missile Museum is located at Launch Complex 26 at Cape Canaveral Air Force Station, Florida.
It includes artifacts from the early American space program and includes an outdoor rocket garden displaying rockets, missiles and space-related equipment chronicling the US Air Force.
The museum is accessible to the public as a part of a daily "Cape Canaveral: Then and Now" tour offered by the Kennedy Space Center Visitor Complex.
Free tours are also offered by the Air Force 45th Space Wing Community Relations office.
The Air Force Space & Missile History Center, a companion to the museum, is open to the general public six days a week.
The History Center is located just outside the south gate of Cape Canaveral Air Force Station. 
The museum was originally called the National Air Museum when formed on August 12, 1946 by an act of Congress and signed into law by President Harry S. Truman.
Some pieces in the National Air and Space Museum collection date back to the 1876 Centennial Exposition in Philadelphia after which the Chinese Imperial Commission donated a group of kites to the Smithsonian after Smithsonian Secretary Spencer Fullerton Baird convinced exhibiters that shipping them home would be too costly.
The Stringfellow steam engine intended for aircraft was added to the collection in 1889, the first piece actively acquired by the Smithsonian now in the current NASM collection.
After the establishment of the museum, there was no one building that could hold all the items to be displayed, many obtained from the United States Army and United States Navy collections of domestic and captured aircraft from World War I.
Some pieces were on display in the Arts and Industries Building, some were stored in the Aircraft Building (also known as the "Tin Shed"), a large temporary metal shed in the Smithsonian Castle's south yard.
Larger missiles and rockets were displayed outdoors in what was known as Rocket Row.
The shed housed at large Martin bomber, a LePere fighter-bomber, and an Aeromarine 39B floatplane.
Still, much of the collection remained in storage due to a lack of display space.
The combination of the large numbers of aircraft donated to the Smithsonian after World War II and the need for hangar and factory space for the Korean War drove the Smithsonian to look for its own facility to store and restore aircraft.
The current Garber Facility was ceded to the Smithsonian by the Maryland-National Capital Park and Planning Commission in 1952 after the curator Paul E. Garber spotted the wooded area from the air.
Bulldozers from Fort Belvoir and prefabricated buildings from the United States Navy kept the initial costs low.
The space race in the 1950s and 1960s led to the renaming of the museum to the National Air and Space Museum, and finally congressional passage of appropriations for the construction of the new exhibition hall, which opened July 1, 1976 at the height of the United States Bicentennial festivities under the leadership of Director Michael Collins, who had flown to the Moon on Apollo 11.
The Steven F. Udvar-Hazy Center opened in 2003, funded by a private donation.
The museum received COSTAR, the corrective optics instrument installed in the Hubble Space Telescope during its first servicing mission (STS-61), when it was removed and returned to Earth after Space Shuttle mission STS-125.
The museum also holds the backup mirror for the Hubble which, unlike the one that was launched, was ground to the correct shape.
There were once plans for it to be installed to the Hubble itself, but plans to return the satellite to Earth were scrapped after the Space Shuttle "Columbia" disaster in 2003; the mission was re-considered as too risky.
The Smithsonian has also been promised the International Cometary Explorer, which is currently in a solar orbit that occasionally brings it back to Earth, should NASA attempt to recover it.
