The Waco Aircraft Company (WACO) was an aircraft company located in Troy, Ohio, USA. Between 1919 and 1947, the company produced a wide range of civilian biplanes.

The company initially started under the name Weaver Aircraft Company of Ohio but changed its name to the Waco Aircraft Company in 1928/29.

Company name

WACO (referring to the aircraft) is usually pronounced "wah-co"[1] (the first syllable pronounced as in "water"), not "way-co" like Waco, Texas, whose name is entirely unrelated. The name comes from a field near Troy, Ohio - Waco field, which in turn received its name from a local war-cry, which had several variations. Although an acronym, the company was universally referred to as "Waco".[citation needed]

Several companies operated under the Waco name, with the first company being the Weaver Aircraft Company, a firm founded by George E. Weaver, Clayton Bruckner, and Elwood Junkin in 1920 in Lorain and Medina, Ohio after they had already been collaborating for several years. In the spring of 1923 this became the Advance Aircraft Company in Troy, Ohio, after the departure of Weaver.

At some point (when is not at all clear from the records but 1928 or 1929) it was changed from Advance Aircraft Company to Waco Aircraft Company. The firm is often confused with Western Aviation Company, the name of four unrelated aircraft enterprises in Chicago, Illinois; San Antonio, Texas; and Burbank, California.

History

Waco's history started in 1919 when businessmen Clayton J. Brukner and Elwood Junkin met barnstorming pilots Charley Meyers and George Weaver. Although their initial floatplane design was a failure, they went on to found the Waco company in 1920 and established themselves as producers of reliable, rugged planes that were popular with travelling businessmen, postal services and explorers, especially after the company began producing closed-cabin biplane models after 1930 in addition to the open cockpit biplanes.

The Waco name was extremely well represented in the US civil aircraft registry between the wars, with more Wacos registered than the aircraft of any other company. Production types including open cockpit biplanes, cabin biplanes and cabin sesquiplanes (known by Waco as Custom Cabins) as well as numerous experimental types.[citation needed]

During World War 2, Waco produced large numbers of military gliders for the RAF and US Air Force for airborne operations, especially during the Normandy Invasion and Operation Market Garden. The CG-4 Hadrian was the most numerous of their glider designs to be produced. At the same time Waco produced over 600 of its UPF-7 open biplanes and 21 VKS-7F cabin biplanes for the Civilian Pilot Training Program, which supplemented the output of the military training establishments. 42 privately-owned models of sixteen types were impressed into service as light transports and utility aircraft with the USAAF under the common designation C-72/UC-72.

The Waco company ceased operations in 1947[2], having suffered the fate of a number of general aviation companies when an anticipated boom in aviation following World War II failed to develop.[3] The final Waco relied on an experimental Franklin engine which, with the cancellation of other contracts became so expensive the Aristocraft that relied on it was cancelled.[4]

The Waco name was briefly revived for a scheme to produce a series of Italian lightplanes under licence in the US.

The WACO Classic Aircraft company (unrelated to the original Waco) began building its WACO Classic YMF in 1986, an upgraded version based on Waco's original type certified design[5].

A large number of survivors exist, with the largest single collection residing at the Historic Aircraft Restoration Museum at Dauster Field near St Louis, Missouri.[6].

Models

Note: Waco civilian designations describe the configuration of the aircraft. The first letter lists the engine used, the second the specific type, and the third the general series. The coding system was changed in 1929 with several letters reassigned, and later with the introduction of the Custom Cabin series, the third letter 'C' was initially replaced with C-S (Cabin-Standard) and finally S.[7] The numeral suffix represents the first year of production if it is 6 or higher (6=1936), or a sub type if 2 or less. Thus EGC-7 is a Wright R-760-E2 (350hp) engined, cabin biplane airframe, custom cabin model first manufactured in 1937.[8]
