[1][2] The basic design, common to both models, was that of a low-wing cantilever monoplane of all-metal construction with side-by-side seating for two in a fully enclosed cabin.

[4] The aircraft structure incorporated a framework built up of welded steel tube which extended lengthwise from the engine firewall to the rear of the cabin, and spanwise from one undercarriage well to the other.

[4][5] Meyers parachuted to safety, sustaining a broken ankle,[4] and although the aircraft was destroyed, its steel inner structure was salvaged and used to build the second prototype.

[5] Only twenty MAC-145s were built, each to a specific customer order, a business strategy that insulated the Meyers company from the poor market conditions that bankrupted many small American aircraft manufacturers in the late 1940s.

[3][4] The type was never produced by Rockwell, and the design again changed hands as part of the Meyers package when sold to Interceptor Corporation in 1968 and subsequently to Prop-Jets Inc in 1982.
