A blog called “GoodShit” has a great set of World War 2 era before and after photos of the Lockheed Burbank Aircraft Plant that was camouflaged with netting and paint to appear like any other Burbank suburb from the air.
Lockheed was a huge military aircraft manufacturing center, as well as an active P-38 fighter base. At this facility they manufactured the famous Lockheed P-38 Lightening, the Lockheed Hudson bomber, Lodestar bomber and the P2V Lockheed Vega. A logical target for the enemy.
Two web readers at Think or Thwim, who picked up on the story, pipe in with the legend of Jack Warner erecting a sign to deter Japanese bombers from mistaking his studio for the now hidden war factory.
The result? A twenty-foot arrow pointing to Burbank, along with the words: LOCKHEED – THAT-A-WAY!
