Pima Air & Space Museum

Spread across 80 acres of Arizona desert, the Pima Air & Space Museum holds more than 400 retired aircraft, including a Boeing VC-137B that carried Presidents Eisenhower and Kennedy as Air Force One before its retirement in 1998.

Here is a detailed Overview of the plane:

Air Force One rarely changes, which makes recent news notable: a $400M Boeing 747 gifted by Qatar entered service as the newest one this month, only to be pulled from service weeks later for upgrades. It marks just the third generational change to the fleet since the jet era began, the latest turn in the story of the select aircraft that carry the sitting US president.
