This discussion, that started as one about whether to hold the release
during an aerotow launch, has focussed on the risk to the glider pilot if a
wing drops during the launch and subsequently migrated to become a debate
about winch launch techniques.

The poor chap who has been forgotten in all this is the tug pilot! Over
the years a number of tug pilots in different countries have been killed by
glider pilots getting out of position and going too high too quickly. This
results in a big reduction in the tug's airspeed towards the stall, and
since it no longer has enough elevator authority the glider raises the
tugs tail and points it at the ground. Below about 700' a tug upset is
probably fatal for the tug pilot - but only a minor inconvenience to the
glider pilot.

Tug upsets, once triggered, occur in a very short elapsed time period -
probably two or three seconds. This does not give the glider pilot time to
search for the cable release and pull it so as to save the tug pilot's
life.

On aerotow a glider pilot should have his hand touching the release, or
holding a loop of nylon connected to it, if the stick movement would
otherwise be restricted until at least 1,000'. Tug pilots are doing you a
service. Respect them by being able to release instantly if the tow goes
wrong.

One entry in this thread stated that tows can be very rough and that the
release might get pulled by accident. Much better that than kill a tug
pilot.
