A Huey was lost near Saigon when it flew into a Kite string made up of Army issue Comms wire.....and the wire wrapped up around the Main Rotor links to the Stablizer Bar.
The tension on the Kite String (wire) caused the two links to pinch closed against the Mast thus causing a flight control failure.
That put an end to cutting Kite strings for fun.
Ten or so people killed in the crash as I recall.
