I always thought that shark picture of the guy hanging from the helicopter was photoshopped. Not 100% sure though.
Helicopter Shark is a composition of two photographs that gives the impression that a Great white shark is leaping out of the water attacking military personnel climbing a suspended ladder attached to a special forces UH-60 Black Hawk helicopter. The photo was widely circulated via email in 2001, along with a claim that it had been chosen as “National Geographic Photo of the Year”. The final edited photo was created by combining a photograph of a HH-60G Pave Hawk helicopter taken by Lance Cheung for United States Air Force (USAF), and a photo taken by South African photographer Charles Maxwell. While the helicopter photo was in fact taken in front of the Golden Gate Bridge, the photo of the shark was actually taken in False Bay, South Africa. There are no known sightings of Great White sharks in San Francisco Bay.
