The only time I have ever seen a tow rope break is during an
intentional rope break manuver. I have been flying the big Nevada and
Eastern Sierra air since 1968, as a glider pilot, tow pilot, air
ambulance driver (rotorcraft). I have thousands of hours flying the
east side in all kinds of conditions (many hundreds of flights in wave
and rotor conditions). Mark, something seems odd about your
descriptions and experiences. Are you getting professional assistance?
Please do not take my post as a slight, as it is not meant to be
degrading.
