The museum has "Columbine III" (a slightly newer Super Constellation), which was also used by Eisenhower. It was delivered to them soon after it was retired in 1966.

I saw this plane decades ago when it was in an auxiliary hanger, before being moved to its present location. It was in decent shape then (you were allowed to walk through it), and hasn't spent decades sitting outside.

Obviously, Columbine III is not in flyable condition, and will likely never fly again.
