Butler International was a United States company in the airplane service, trucking, and technical-management industries. Founded as the Chicago, Illinois–based Butler Aviation in 1947, the company spread across the United States and acquired various other aviation companies, becoming by 1970 the country's largest aviation services company. In 1974, reflecting a diversity of business interests and services in Europe, it was renamed to Butler International. Once a "giant of the general aviation industry", the aviation division was sold in 1992 and merged in 1998 into Signature Flight Support, a company run by the British company Signature Aviation. The rest of the company was sold and ultimately declared bankruptcy in 2009, acquired by Butler America,[later Butler Aerospace & Defense, a subsidiary of Select Staffing. This successor company, now owned by Indian conglomerate HCL Technologies, works almost entirely as a technical and engineering support provider for Sikorsky Aircraft Corporation
