Pretty weak museum.
We went to the public library to get culture passes which allow 2 free entrances.
The museum really doesn't have anything to offer. There are a few interesting pictures on the wall and a few models of the challenger but really nothing else to see or do.
They have a few computers with Microsoft flight simulator so you can do some loops and rolls on the computer before you leave.
I wouldn't waste my time or money coming back here and I certainly wouldn't recommend this as a fun Phoenix activity.
