AIRCRAFT WAS ON A MISSION TO SLING OUT THREE CONEX CONTAINERS FROM AN AREA IN WHICH THERE WERE SEVERAL HIGH ANTENNAS AND A 35 FOOT STEEL TOWER. THE BASE OF THE TOWER WAS LEVEL WITH THE TOP OF THE CONEX DUE TO THE GROUND SLOPE. THE DISTANCE FROM THE NEAR EDGE OF THE TOWER TO THE NEAR EDGE OF THE CONEX WAS 49 FEET. IT WAS DETERMINED BY THE AIRCRAFT COMMANDER THAT A 100 FOOT SLING WOULD BE REQUIRED TO SAFELY PERFORM THE MISSION. THE AIRCRAFT DEPARTED THE AREA AND RETURNED TO LIFTMASTER PAD TO PICK UP THE SLING. AT 1615 HOURS THE AIRCRAFT RETURNED WITH A 100 FOOT SLING WHICH WOULD ENABLE THE AIRCRAFT TO PICK UP THE CONEX WHILE HOVERING AT AN ALTITUDE HIGH ENOUGH TO CLEAR THE TOWER AND ANTENNAS. ALL THREE CONEX CONTAINERS WERE PLACED TOGETHER AND THE AIRCRAFT COMMANDER LIFTED THE FIRST TWO WITHOUT INCIDENT. ALL THREE APPROACHES WERE MADE ON A HEADING OF 030 DEGREES INTO THE WIND, TERMINATING WITH THE TOWER TO THE RIGHT REAR OF THE AIRCRAFT. THE PILOT WAS HOVERING OVER THE THIRD CONEX WHEN THE AFT ROTOR STRUCK A STEEL VERTICAL BEAM SEVERING IT APPROXIMATELY 1 FOOT FROM THE TOP OF TOWER. AT THIS TIME THE AIRCRAFT WAS VIBRATING EXCESSIVELY AND THE AIRCRAFT COMMANDER GOT ON THE CONTROLS WITH THE PILOT. THE AIRCRAFT DRIFTED TO THE LEFT, AWAY FROM THE TOWER, AND THE NOSE OF THE AIRCRAFT TURNED 80 DEGREES TO THE RIGHT BEFORE LANDING ON A ROW OF CONSERTINA WIRE. ENGINEER STAKES HOLDING THE WIRE PUNCTURED THE BELLY OF THE AIRCRAFT.\\
