Aero Spacelines was sold in August 1965 to Unexcelled, Inc., a publicly-traded company that had subsidiaries engaged in discount store retailing, meatpacking equipment and iron castings. Unexcelled also owned American Airmotive Corporation, an aircraft maintenance and repair organization.

(CAB) gave Aero Spacelines an exemption permitting them to offer Guppy transport services to the public. The CAB was a now-defunct federal agency that, at the time, tightly regulated almost all US commercial air transport. The CAB's permission was required for Aero Spacelines to offer air transport services to the public.
By November 1968, NASA had paid Aero Spacelines $11,591,633 in contracts.
In 1972, Unexcelled changed its name to Twin Fair, the name of its retailing subsidiary. In 1981, Twin Fair sold Aero Spacelines to Tracor, which dropped the name in favor of Tracor Aviation.
