Occurred on March 2019 / Otay Lake, California, USA
Info from Licensor: "Many attempts have been made to build and fly a large pterodactyl. I decided to give it a try. I shaped a bunch of foam blocks into a 30-foot pterodactyl, installed a thrust and control system and built a takeoff cart. We received permission to use a Parachute Training facility for testing. The bird weighs 50 pounds and flies very well. The flight was conducted by the designer, Otto Dieffenbach, at Otay Lake, California in early 2019. Otto is an accomplished modeler and retired Aerospace executive. He operates an Identifiable Flying Objects Company called Flyguy Promotions."
