A photo captures a shark attacking a diver climbing into a helicopter.

See the email here.

No, it's a fake.

The photograph is a juxaposition of two genuine photographs.

Here's the helicopter and diver sans shark:

And here's the shark:

The photograph of the helicopter is used in a web page describing the U.S. Air Force's HH-60G Pave Hawk helicopter.

The photograph of the jumping shark was taken by underwater photographer Charles Maxwell off the coast of South Africa.

The anonymous Photoshop hacker flipped the picture of the helicopter and diver and pasted in the jumping shark.

As Photoshop phakes go, this one is better than most. No obvious artifacts point to digital manipulation of the picture.

Unfortunately, the backing story is not of the same quality. The Golden Gate Bridge is left in the background which is somewhat at odds with the caption that claims it happened in South Africa. More proofreading wouldn't have hurt as well.
