My observation on setup of the airplane mission is that is the line is too
tight, then the airplane may not release.
The tautness is specified in the Field Setup instructions:
  "Finally, use the thumb-gear at the arrival end to put tension on the
string until the cantilever (tire/arm weight) sits mostly level."

If the airplane does not release during a tournament match, then the
scoring follows Rule 34, Model Damage, Bullet 6:   "Any model damage
obviously due to poor setup or lack of maintenance is scored with benefit
of the doubt."
