Real event, faked photo
"The photo is obviously fake. The plane wouldn't have created such a huge
plume of water. And how likely is it that someone would have managed to
capture a picture of the scene at exactly the right moment? And if you look
closely, you can see several people in the lower-right corner who have their
backs turned to the bridge. In real life, the noise of the jet would have
caused everyone to look in that direction."
