Very well run quality museum! We asked for and got a volunteer guide who enabled us to go inside several aircraft. He tailored our tour perfectly, we had children with us, and kept it interesting and fun. The displays inside, and the planes outside are very cool. This is a free museum but after going, and appreciating the work and knowledge of the volunteers, I'd recommend giving a donation, there's a jar by the museum shop. Oh, by the way, they have real and unique (made in) Hawaiian shirts for sale there.
