Sikorsky S-67 - The first Blackhawk

Based on the S-61F and the S-66 ( the Sikorsky's motion for the original US Army 's 1965/6 AAFSS competition ), the S-67 Blackhawk was a Sikorsky 's private venture intended to replace the ill-fated Lockheed AH-56 Cheyenne. The US Army chose the Hughes 77 (as the YAH-64) and the Bell 409 (YAH-63) to be the contenders in their new AAH competition therefore the S-67 was cancelled. The lone S-67 prototype crashed while conducting demonstrations at the Farnborough Airshow in September 1974. Both crewmen were killed.
