We need not worry so much about the flying to the end and the jerk.

In all the 'end of line' encounters with Tinkerbell, she just kind of
swivel onto a new direction. None of those 'hitting a brick wall'

I wondered over that before and decided it was a matter of applied

First of all, our arm holding the line, the line, and her body all have
a certain 'looseness' and give to them. The jerk is not an
abrupt 'hitting of brick wall'.

When they fly, their center of gravity , CG, is not and never will be
at the point of tether to the harness. To be more explicit, that CG
will be at the point of tether if that tether can be threaded
physically through the heart. The stop will then be abrupt, but then,
with the tether through the heart, you need not worry about her flying
fast or even flying at all.

That meant the CG is off-set away from the line. The point of
attachment of the tether to the harness acts as a hinge. So when the
end of line is reached, the body kind of rotate around onto a new

Tinkerbell knew it. There had been many times she deliberately flew to
the end of the line away from me to twist at the end to fly in big
circles a few times before returning back to me again.
