there was recently a photo circulating on the internet
of a training maneuver of a naval squad where a diver
was suspended from a helicopter by a ladder, and a
shark was leapoing out of the water attempting to
take a bite out of him or devour him.

this photo ws going around a few years ago
as it turns out it was a hoax..two pix
cut and pasted...one of copter training
and another of a shark in south africa.
