| When large hail falls with strong winds, it can become a deadly projectile. Ranchers
across America tell stories about hail storms that had killed their cattle because they
were trapped in an open field during a thunderstorm. Scientists commissioned by the
National Geographic television channel studying the remains of 200 people buried in
Himalayas dating from the 9th century found that Giant hail apparently killed them.
According to the Guinness Book of World Records, the heaviest hailstones on record
weighed up to 2.2lb and killed 92 people in Bangladesh in 1986.
