What is the average time spent at the museum?

I easily spent two hours plus with my family, would have liked to have spent more

I'd estimate 2.5 hours

I was there 4 or 5 hours.

I'd say 2 to 3 hrs but you'll want to go back for more theres so much to see and do. The resto shop was my favorite

I would count on 2-3 hours, more if you are really interested in aviation history. I could easily spend an entire day.
