The rocket flight will be timed. Contestants with the longest flight duration times win. Rockets shall be recovered only by parachute. Rockets must descend as one connected piece as a typical model does. If the rocket separates into multiple pieces, or the parachute does not deploy, that flight shall be disqualified.
Contestants can make two flights if desired with the combined times being their score.
Timing shall begin at the first motion of the rocket and end when the rocket touches down or can no longer be seen by the timer. This includes the rocket coming to rest in a tree or on a building, or going out of sight behind them. In the case of a stop-watch malfunction or timer error, the contestant has the option of making another flight. Scores are determined by the time in seconds of flight of the rocket. The object of this event is to land a rocket closest to a marker in the field.
