10 *feet* ???!!!!

When I watch a glider taking off, the tow rope is entirely clear of
the ground as soon as the tow plane has taken up slack and started to
accelerate, and this continues to be true when the glider is just off
the ground (in case you argue there is more tension when the glider is
rolling on the ground).

The sag might or might not be a bit more than 10 inches, but it's
certainly nowhere near ten feet!
