McCulloch emigrated to the US in 1927 and worked for a small machining company before joining the Atlantic Aircraft Corporation.

Other members of the initial management team included: Al V. Graff, general superintendent; Clyde Williams, secretary & assistant treasurer; Joseph H. Baylis, industrial relations; Howard Jones, plant engineering, Ted H. Beck, aircraft engineering; Charles D. Collier, purchasing; John A. Maxwell, Jr., manufacturing control; Robert Yonash, production engineering; J. D. McKelvain, inspection; Otto Witbeck, shop superintendent; and O.

Bankers were unimpressed with the plan, but they eventually secured financing from several sources, notably Col. D. Harold Byrd who would later serve with the company.

Equipping the Swift with a much more powerful engine and tandem two-seat cockpit turned it into the T-35 Buckaroo trainer aircraft, which competed and lost out to the Beechcraft T-34 Mentor.

In 1955 they won a contract to produce "quick reaction kits" for the Air Force's B-29 Superfortress fleet, and employment started increasing again.

In 1952 they started work on what would become the Model 51 Pinto, competing with an Air Force contract that was eventually won by the Cessna T-37.

Together the two firms raised capital from various sources, and in 1961 formed a merger with Chance Vought, who had moved to the area in 1948, to become Ling-Temco-Vought, or LTV.

The former Temco Aircraft electronics plant at Greenville, by then known as LTV Electrosystems, became E-Systems, eventually being purchased by Raytheon, and today is a part of L3Harris known as L3Harris ISR Systems.
