Minimum Distance / MND
After pilots fly fixed interval (about 30 or 45 min.), they drop their marker. The distance between the point its marker has dropped and the target set in the takeoff area should be shorter. The winner who made the shortest distance gets 1000 points. The key point is that how they keep not to move in the sky or how they come back to the takeoff area.
