During WW II Lockheed (unbelievable 1940s pictures). This is a version of special effects during the 1940's. I have never seen these pictures or knew that we had gone this far to protect ourselves. During World War II the Army Corps of Engineers needed to hide the Lockheed Burbank Aircraft Plant to protect it from a possible Japanese air attack. They covered it with camouflage netting to make it look like a rural subdivision from the air. Click the photo below to see more.
