Check out the book "Chicken Hawk" by Robert Mason, who flew Hueys in combat in Vietnam. These pilots were able to pilot in and out of some very dangerous situations using the unique qualities of the aircraft. I remember one involved taking off from a hilltop artillery battery by using gravity to drop the aircraft backwards off the steep hill after making a dropoff, or landing in a jungle using the rotors to chop away the vegetation (branches and leaves only, not trunks) to verify that a crashed U.S. aircraft had no survivors. He also talked about a stunt that another helicopter attempted to do, lifting a heavy pole or beam without the proper stabilization which resulted in uncontrollable spin and the death of all aboard.
