How Helicopoters fly.

Myth: Helicopter fly
because they are so ugly
that the earth repels
them.
Myth: Helicopter drop
from the sky when the
engine fails.

Truth: They auto rotate
to the ground safely
under control.

Truth: Anyone can fly an
airplane, they want to
keep flying.

Helicopters do not.

Myth: Helicopter pilots
eat the mints out of the
urinals.

Truth: Its the stuck wing
(airplane) guys!
