Rescue helicopters are easy to control the flight altitude quite feely and suitable for saving survivors at sea. Especially, compared to planes, helicopters have being used for rescue because they can fly lower. However, when helicopters fly low, it makes a lot of accidents because of the low level flying. 80% of helicopter accidents are caused by the propellers. The main reasons are wind effects, crash with obstacles and irregular work of propellers. I suggest airpeller to solve these problems.
