The driver

Fire Authorities in California found a corpse in a burnt out section of
forest while assessing the damage done by a forest fire. The deceased male was
dressed in a full wet suit, complete with a dive tank, flippers, and face mask.
A post-mortem examination revealed that the person died not from burns, but from
massive internal injuries. Dental records provided a positive identification.
Investigators then set about determining how a fully-clad diver ended up in the
middle of a forest fire. It was revealed that, on the day of the fire, the
person went for a diving trip off the coast - some 20 miles away from the
forest. The firefighters, seeking to control the fire as quickly as possible,
called in a fleet of helicopters with very large buckets. The buckets were
dropped into the ocean for rapid filling, then flown to the forest fire and
emptied. You guessed it. One minute our diver was making like Flipper in the
Pacific, the next he was doing a breaststroke in a fire bucket 300 feet in the
air. Apparently, he extinguished exactly 5'10" of the fire.
