Double Release Failure

Just to add two thoughts- 1) the wake is more mild as the tug is
generating less power, 2) it worked best for me (and this is how I was
taught) if the sailplane controls the descent rate and the towplane
controls the speed. This division of duties prevents the towplane from
landing too short. Also, at towplane final approach speed, the glider
will be well above stall and clearly not ready to land. Thus it is
natural for the glider pilot to keep it flying and apply just enough
spoilers are needed at this point to keep the rope taught. The
maneuver is uneventful if properly planned out, but it does eat up lot
of runway.
