National Helicopter Museum National Helicopter Museum traces the evolution of the rotary wing from early predecessors like the boomerang and Chinese tops to designs by Leonardo da Vinci and George Cayley to early motorized experiments to modern helicopters of today. Igor Sikorsky's first helicopter success in Stratford on September 14, 1939 is documented as well as his subsequent productions. Also displayed are the small gas turbine engines developed locally by Dr. Anselm Franz at Avco Lycoming which power such helicopters as the Bell Helicopter UH-1 Iroquois or "Huey" and the Boeing CH-47 Chinook. Other exhibits include ones on tilt rotor development; current photos
Boeing CH-47 Chinook in June 2005 with all aboard killed, including a 16-member U.S. Special Operations team. In May 2011, an Australian Army CH-47D crashed during a resupply mission in Zabul Province, resulting in one fatality and five survivors. The helicopter was unable to be recovered and was destroyed in place. To compensate for the loss, the ADF added two ex-U.S. Army CH-47Ds to the fleet which are expected to be in service until the introduction of the CH-47Fs in 2016. Since the type's inception, the Chinook has carried out secondary missions including medical evacuation, disaster relief, search and rescue, aircraft recovery, fire
