Does anyone use a tug tow hook that releases automatically whenglider kites?

Thanks Chris - appreciate your comments!

Apologies if I interpreted it incorrectly.

I think Chris has made it pretty clear that the fitting of an automatic
system is not at this time a practical solution. I think he has also made
it pretty clear that once the sequence starts the result, as far as the tug
is concerned, is inevitable.

This is one of those situations where tug pilots are going to have to
decide what risks they are willing to take. I would support any tug pilot
who said that he would not tow a glider on a CoG or Compromise hook. On the
other hand I would not tell him he could not do it. There is also a
responsibility for those of us who teach aerotowing to really get across to
students the danger, to the tug pilot, of getting out of position. I am not
sure we have done this in the past, I know I have not been as pedantic as I
should in getting this point home.
Tug pilots do not always know the people they are towing so they are
perhaps not aware of the experience, or lack of it, of the pilot on the
back. In those circumstances the saviour should be the authoriser. We all
know that does not work. Perhaps tug pilots need to be more circumspect in
who they are prepared to tow.
