1935 WACO Model YOC

WACO built a variety of open-cockpit and cabin aircraft before and during World War II. These sturdy aircraft were generally regarded as solid, dependable performers and were very popular. The enclosed cabin biplanes, called Cabin WACOS, were especially sought after. The WACO YOC differed from its predecessors by having a shortened lower wing and elliptical wingtips. The cabin was also widened to accommodate three passengers in the rear seat. In spite of its bulkier configuration, it was 7 MPH faster than the smaller WACO "Standard" with the same horsepower. The physical design was clearly WACO, but the lines of the aircraft reached a level of elegance unusual in planes of this era. One YOC was impressed by United States Army Air Force as the UC-72N during World War II.

The Custom Cabin WACO was a particularly elegant aircraft but was quite pricey for the era, around $7995, so it would most likely be owned by successful companies or individuals of means. One such individual was Walter Mathew Jeffries, who designed the original Starship Enterprise for the "Star Trek" television series and film.

He obtained an aircraft that was previously owned by the State of Indiana. He donated the aircraft to the Virginia Aeronautical historical Society which in turn loaned it to the Virginia Air Museum.)

The Star Trek Enterprise was a cruiser of the starship class. Its registration number, NCC-1701, was inspired by Jeffries' own 1935 Waco YOC airplane, which was registered as NC-17740.
