There will be 4 concentric rings on the field.  The object will be to land within the circles on the field.  The total score will be the sum of the zone that the plane lands, plus the zone that the plane comes to rest in.  A timer will begin when the plane leaves the ground and will end when the plane comes to rest.  Time will be a tie breaker within equal scoring points.  Scoring:  100 points for center, 70 points next outer, 50 points next outer, and 10 points for outer most.  The total score will be the sum of both points.  If a plane touches down in the center but rolls out of the outer most circle, the total points will be 100.  If the plane touches down and stops in the middle zone, the total score will be 200 points.
