This might be one of the coolest old photos we have discovered. It shows a squadron of bombers flying over Washington in 1931. The main road in the picture is Pennsylvania Ave. heading toward the White House. Click on the image for a larger version. It’s quite detailed, so tell us what you see in the comments below. I think I can make out Connecticut Ave. in the distance.
