It was my maybe third visit last week and did not find it boaring at all despite the fact that none of the displayed aircrafts were real.
Saw children, men, elderly people equalilly exited to see all the stuff on display. Parents putting children on gunner bay and taking snaps. Some looking at small scale models, some at the big python skin while others adoring tribal dresses.
Definatly worth a visit, i only wish that they increase the display items and area. Apart from peak, elephant falls this is the other point that all tourists go.
I had to show my ID to get in, just driving license was enough.
