AIRCRAFT

1 / Corsair glider from Free Paper Planes by Corneles Huisman at: http://www.geocities.com/EnchantedForest/Creek/8015/. This is listed as a Corsair -- but it really is a Hellcat.
It is a profile model designed as a glider, but I am quite sure it will not fly nearly as well as standard fold-up paper planes. Made and photographed by M. Carbone

without any groans, grimaces or tears.
