My Cali friend captured this close-up photo of a UFO hovering over the Golden Gate Bridge last night. It's surreal.

What do you make of it? It's almost transparent like it's trying to blend in with the surroundings. My friend said he saw it while driving with 2 of his friends and they decided to get as close as possible to it out of disbelief. He said it kept flashing a white light inside of it and a green emerald color light on the bottom. It was the only photo they were able to take of it because their cellphone batteries died. He also said he edited out the left and right because his friend's were in the photo giving a thumbs up so that's why it's small but still I've seen no other photo like it in my life. I think it might be some secret military aircraft.
