Reverting to the original point of this thread, please note the total absence of fences, we used to be able to walk straight on to the apron (called “ramp” in more recent times) in those days!

When do Commercial subjects become Historic?
Is there are “cut-off” year? Or are commercial propeller-driven aircraft historic and passenger jets commercial?
I have some lovely VC-10 pics from 1968 and wonder where I should post them, if I ever do.
Please note that this is a serious question!

I’m using “USAAF Fighters Part1” by them, the only alternative would be the CW-24B, which I doubt it can be!

There may not be a proper answer to that question, since thousands of components and sub-assemblies were made in hundreds of different factories, the photos show final assembly, which is perhaps what you would like to know about. In other words, starting with a kit of parts, how long did it take to put one complete aircraft together? Is that what you mean? Perhaps some retired production manager could tell us!

I think number 4 must be a Curtiss P-55 Ascender

Thanks, jeepman, just added that link to my Web Favourites . . .

Well done, Jochen, it pays to get there early before the aircraft become hidden by crowds of people!
