Design and development

The K-W glider was assembled from a collection of certified

Operational history

The K-W prototype was completed and flown in 1957 and accumulated 390 hours, the majority of which had been flown by Kennedy's two teenaged sons. The K-W was being flown by a 27-year-old

identified the likely cause factors as that the pilot in command mishandled the flight controls and exceeded the stress limits of the aircraft. The NTSB also cited the pilot's lack of familiarity with the aircraft type. No further aircraft of the type were constructed.


Variants

;Kennedy K-W :Original prototype, destroyed in August 1975. ;Dart Aero-5 :Second aircraft built along the same lines. The fuselage was an original design, but the fin and rudder from a Taylorcraft were used, along with Aeronca wings. A later owner was reportedly constructing a new set of longer, all-metal wings for the aircraft in 1983. As of May 2011 this aircraft was still registered with the Federal Aviation Administration and based in Milo, Iowa.
