These paper gliders were designed by a NASA Engineer/Artist and are detailed replicas of two of the most famous WWII Fighters, The P-51 MUSTANG and The Voight F-4U CORSAIR. Also included are two famous Jet fighters - The F-14 TOMCAT and The F-16 FIGHTING FALCON. The other four gliders are fun experimental aircraft deigned by the artist. For a limited time we will include the F-15 Falcon glider for FREE. These paper planes can be built for display or for flight. They are recommended for ages over 10 or with assistance from an adult. An Exacto knife works best for cutting out and use of either tacky glue or a glue stick is recommended. The assembled models are about 6" long with a wingspan around 5".
