Davis Monthan Air Force Base.

Davis Monthan Air Force Base is located in Tucson, Arizona. I have visited this spectacle many times, and I must say, it is a sight to see.
In 1925, Tucson bought 1,280 of land, to home the soon-to-be new air force base. They finished building the sight in 1927. On September 23, Charles Lindbergh dedicated the site to two aviators who died in seperate plane crashes after World War 1. It therefore became named as as a mix of the two aviator's names. Davis-Monthan.
The field immediately became the first, and the largest municipal-owned airport in America.
The military came on October 6, 1927.
In 1940, the War Department announced to establish an Army Base in Tucson, because of the rising war in Europe. Many planes and bombardments then arrived at the air port base.
Tucson's dry, and sunny climate made it ideal for aircraft storage, and preservation.
Training jets arrived at the base in February, of 1953.
Since then, many jets, air crafts, tanks, bombing planes, and other military vehicle have arrived at the base. There are more than 300 different types of aircraft and spacecraft in the field. Some are the most technically advanced craft this world has ever seen. They came from not only the United States, but the entire world!
Even today, it is still in use, should an emergency come forth.
Also, it can be viewed in a museum, with the cost of admission. It is open every day of the week, from 9:00 a.m. to 5:00 p.m. The latest you can arrive for a tour is 4:00 p.m. The only days it is actually closed throughout the entire year, is on Thanksgiving and Christmas Day. Parking is free. And you can even bring your pet if you wish. You can pay for a tour with a group, as well as admission, or you may prefer to walk to the exhibits on your own, taking your time. Either way, you still need to purchase tickets to view the museum.
Also, there is an Inn on the reservation, which houses 50 temporary lodging facility. There are options between one bedroom, and two bedroom rooms. The customers are held in top priority. And it is basically first-come, first-served.
The museum is one of the largest air and space museums in the entire world. It's also the biggest non-government funded aviation as well.
