While visiting Hawaii a friend at work took a photo of the American flag flying above the U.S.S. Arizona memorial which he proudly uses as his background on his work computer. Upon close inspection of the photo I noticed that there are two American flags flying together on the one pole. The larger American flag flying at full mast plus a smaller (perhaps 3x5) American flag that is flying centered together with the larger flag. I can't find any photos with this situation or anything online explaining this. My only thought is it could be a ceremonial flag that was flown above the Arizona Memorial that was destined to be presented at a Pearl Harbor survivior's funeral? Anyone know it's purpose?
