At risk of making myself look daft because I've mis-remembered the
signals, I'm pretty certain that here in the UK rocking the glider's wings
is an indication that you can't release from tow (though it's actually
combined with flying out to the left before giving the signal) and so by
implication, I'd guess, a request that the tug release you at an
appropriate point.


the glider wing rock for cannot release is given AFTER the glider has moved
off to one side of the tow plane (normally left for those side by side
seating tow planes)... not when directly behind the tow..
