The A-26 Invader did originally begin as a private venture on the part of the Douglas plant at El Segundo, California, so at the end of World War Two, it wasn't surprising that surplus Invaders were quickly purchased as high-performance business aircraft with conversions undertaken by On Mark,  L.B. Smith Company,  Lockheed Air Service (LAS), Rhodes Berry, Rock Island Oil & Refining Co, LeTourneau , World Corp, Grand Central Air Services and Aero Trades Inc. , to haul business executives in comparative speed and luxury.

With minimal modifications, such as the removal of some military features, including bomb bay doors sealed shut, passenger entry stairs in bomb bay, and the conversion of the fuselage to accept six-eight passengers. Improvements developed considerably until the early 1960s, when purpose-built executive types started to become available.
