THE AIRCRAFT DEPARTED POND CREEK AIRPORT OKLAHOMA.  THE AIRCRAFT DEPARTED WITH FULL FUEL, 275 GALLONS OF WATER AND 25 GALLONS OF GRAZONNEXT.

A WITNESS WAS VIDEOING OUT OF HIS HOME WINDOW AND CAPTURED THE AIRCRAFT HITTING THE TOWER GUY WIRES.  THE VIDEO SHOWS ALL FORWARD MOTION OF THE AIRCRAFT STOP WHEN THE AIRCRAFT CAME IN CONTRACT WITH THE GUY WIRES. THE AIRCRAFT FALLS TO THE GROUND. THE AIRCRAFT FALLS IN A NOSE DOWN RIGHT WING DOWN ATTITUDE.

A TOWER SECURITY CAMERA MOUNTED ON THE TOWER SHOWS THE AIRCRAFT IMPACT THE GUY WIRES AT 1712. THE VIDEO SHOWS THE TOWER BEGINS TO VIBRATE AND GUY WIRES MOVING PAST THE CAMERA. THE CAMERA RECORDS FOR APPROXIMATELY 23 SECONDS AND STOPS RECORDING WHEN POWER IS LOST.

A WITNESS WORKING ON THE PROPERTY STATED IT WAS THE AIRCRAFT?S FOURTH PASS AND WAS HEADING SOUTH.

THE RADIO ANTENNA TOWER WAS 1040 FEET ABOVE GROUND LEVEL (AGL). THE TOWER HAD A TOTAL OF 30 GUY WIRES EXTENDING TO THE TOWER.
