Kaman HH-43 Huskie Reg. No. N43FK C/N 60-0289 built 1962.
Owner: Kaman Aerospace Corporation, Bloomfield, CT 06002 United States New England.
One of only two airworthy H-43 Huskies worldwide, used for pilot training.
With life-limited blades and no additional blades known, it won't be long before both flying Huskies are retired.
The photo also clearly shows the servo-flap, a hallmark of Kaman's helicopters.
This is used instead of traditional cyclic controls to maneuver the helicopter.
