Sean D. Tucker discusses the design of the Oracle Challenger. The key focus in the design process is speed. From it's composite propeller to the unique concept of 8 ailerons, the Oracle Challenger is an incredible machine. Sean's flying skills won him the U. S. National Advanced Aerobatic Championship in 1988 and he never stopped to look back. His aerobatic performances over the years has earned him the Art Scholl Memorial Showmanship Award and The Bill Barber Award for Air Show Showmanship in 1992. Sean has earned numerous awards since then, culminating in his induction into the National Hall of Fame in 2008. A great pilot and a great plane delivers one of the best aerobatic airshows you will see.
