The pilot will roll 2 dice before the start of the flying part of the event.  The pilot must do 1 roll plus 1 loop (roop) for the number rolled on the dice and then land to roll the dice again.  Time will start when the plane leaves the ground and will end when the pilot rolls his number again after the roops are completed.  The pilot must change direction to initiate the sequential roops (do a 180 degree turn for the next roop).
