I should tell my early-solo students that a missing or stuck yaw string
is sufficient reason for them to make a non-standard pattern, make
deliberately uncoordinated and little-practiced turns near the ground, and
give up the advantage of a correctly functioning IAS? I don't think so!

I once hired an ASK-21 (the one at Turf that crashed recently :-( ), and
on two flights I found after takeoff that the yaw string had got caught
by the front canopy and was inoperative.

It was unnerving at first, but didn't seem to make any difference to
being able to soar sucessfully.
