I visited the US Air Force museum in Dayton, Ohio last week. I hadnt' been there in about 20 years (I went with my Dad on one of our vacations long ago).
A couple of weeks previously, at Oshkosh, I took the fabric covering class for airplane construction and found it very interesting. So at the museum I spent much more time looking at the surfaces of airplanes and interiors than at the airplanes themselves.
An ENIGMA cipher machine. This was the first time that I've been physically in the presence of one that I know of.
This is the tail of a B-24. I do believe that the main part of the fin (on the left) is aluminum, but that the rudder part on the right is indeed fabric-coated.
Detail of a wooden wing rib.
I actually took very few photos of airplanes. This is an F-86 Saberjet with the exterior skin taken off to show the inner parts.
That's all I have for the moment. It was more of an experience to be there again than to take photos. I was only there for a couple of hours.
I'll definitely visit again in less than 20 years.
