What are some of the dangers involved with helicopters?

Malfunction causing the controls to fail leading to a horrific crash(RARE). Storms causing you to lose control of the Helicopter(Unlikely with experienced pilot). and more. but if you are in a helicopter with an experienced pilot and a tested safe helicopter, you will be fine, its just a fear for most people. In winter snow conditions, there is the danger of "white out". When the helicopter approaches for landing, the rotor down wash can kick up the snow and suddenly the pilot finds himself blinded by the whirling snow and he can't see. Tail rotor strikes. The tail rotor is spinning very fast and is large. Pilots sometimes don't realize where the tail rotor is and they swing the helicopter around and hit something with it. Also passengers or ground crew have been known to walk into the blade.(rare with experienced pilot)
