Thought I would finally get around to asking a question that I was supposed to do some time back. the first is does anyone know if the following two photos show a De-tuner base and if so what for, it does not look right for a Vulcan as the pit looks like it would be a nice place to drop the Stb wheels, the only other thing I could think of was for the Blue Steel engine running?
The last picture, the shape is concrete, has several suggestions but it seems to close to the taxi way for it to be a AA gun mount.
