An airship (or a barrage balloon?) over London while searchlights are in action...1940? 1916? No! This picture was taken in London tonight. Almost certainly some sort of marketing action connected to the Olympics. I found the image and the setting quite suggestive, particularly after having written about airships on this blog not long ago.
I know the quality of the image is not perfect, it was taken with a small basic camera from a long distance, Hyde Park, and at night. In the next picture even worse quality but you can see the approximate location of the blip, notice the London Eye on the right side of the picture.
