My first great paper airplane flight was in third grade; I folded a plane similar to the Flyer and with a gust of wind it flew for what seemed 30 seconds. Since that day, I've spent hundreds of hours folding paper in every possible way attempting to replicate that excitement. However, I didn't just want to fly paper airplanes, I really wanted to create the most awesome paper airplane. IMHO, the Spirit is that plane. Even the first versions looked so cool and flew so well that I knew she would change the paper airplane world. For years, the Spirit was top secret. The secret was let out in 2008 when I introduced v.3 to the world in a YouTube video. Then in 2011, the Spirit was featured in "High Fliers: 5 Great Paper Airplane Designs" by Mike Smith of Yahoo Games. While the Spirit has not broken any world records (yet), it does provide a fantastic platform for science teachers to discuss Science, Technology, Engineering, Mathematics or just to inspire and/or motivate students. To be honest, I won't be happy until every science teacher in the USA can fold one.
In any case, the Spirit took me years to master but you can learn it today!
Good luck and enjoy!
