ABOUT THE F-14 TOMCAT
The Hiller H-23 (Hiller Model 360) was built in Palo Alto, California, and used extensively by the US Army for all sorts of activities, but is most known for primary helicopter flight training. The Army had previously acquired the earlier version, called the H-12, from Hiller. The Army acquired about 1,800 of the more than 2,000 that were constructed from the late 1940s until the 1960s. It was retired in the early 1970s.
The Hiller H-23 “Raven” was a unique three-seat observation and training helicopter.
Our H-23 served not only as a training aircraft at Fort Wolters but also served at Army National Guard Base Eagle Mountain Lake. That facility is now part of the Copeland Ministries but was at one time home to an Army tank battalion. We believe our Hiller was used for observation or liaison purposes there.
Its rotor blades are made of wood.
