First flown in 1950, the Horrnet light helicopter was propelled by rotor tip-mounted ramjets. It suffered from very high fuel consumption and noise levels. This example was also registered as N3781G and is here on loan from the Classic Rotors Museum, Victorville.
Originally an anti-submarine warfare HSS-1. Converted to UH-34G and transferred to South Vietnamese Air Force in 1967. Later N586HS. 'RP' on the fuselage appears to be an individual aircraft code; 'DM' is painted on the nose.
The Cygnet was a metal light aircraft first flown in 1937. A batch of ten was built by General Aircraft and during the war, a few were used as liaison aircraft or to give tricycle landing gear training to prospective Douglas Boston pilots.
The clearest shot I ever got of this interesting exhibit at the Aviodrome. After WWII KLM boss Albert Plesman was quick to obtain a number of C-54s. Initially they operated as government aircraft, including wartime orange triangle military markings, until things normalised along the airline's route to the East Indies. This airframe is not the real NL-316 / PH-TCD, which was c/n 10312. Being repainted in KLM colours in 2019 to celebrate the airline's 100th anniversary.
