tow rope brake practice crash, what can we learn...

Except in very strong wind conditions a rope break at or above 200' is
hardly an "emergency". It is a circumstance that requires immediate
action, but appropriate training should make this a routine maneuver,
executed with confidence. A real 150’ rope break becomes a true
emergency at many airports where the glider is going to land off-
airport and the outcome is not certain. The level of training needs to
overcome the “surprise” factor to minimize the delay in reaction
should a rope break take place.
