I believe that it was Ralph Story who showed aerial pictures of one of the major movie studios from that same period. The studio moguls recognized that with the facilities in Burbank camouflaged they looked like suitable targets. They actually put an arrow on the top of their studio buildings pointing towards Burbank!
So Hollywood was full of lefty anti war SOB's back then as well!
That may have been the episode I recall, I was only about 12 then so I am weak on the details.
I do remember my Dad telling me that was all true, he loaded and then later drove trucks during the war ('42-'44) before enlisting when he turned 17 and said he remembers seeing that camouflage.
