Via an IRC chat session today I was led to this thread on the Warbird Information Exchange. It's 54 pages long at the time of writing, and it's chock-full of wonderful photographs of historical US Navy (plus a few other) combat aircraft. I've included a couple of examples here. (Click the images for a larger view.)
I've never seen a collection like it. Many of the photographs are unique in my experience. It's a magnificent resource for aviation fans in general and warbirds fans in particular.
Very highly recommended viewing. I've bookmarked it for (frequent) future reference.
