After the DC-3 and its successors made commercial flight economically viable, large national airlines consolidated and offered regular international service. With a booming global marketplace on the rise, it was critical for corporations to invest in international travel. However, flying frequently on commercial airliners could eat away a company’s resources, resulting in the need for private, business-owned aircraft. Beginning in the 1950s, aircraft manufacturers entered the race to produce a practical private jet.
In 1966, Grumman Iron Works produced a prototype of the Gulfstream GII, the first large, long-range corporate jet. Motorola CEO, Robert Galvin, purchased the N55RG serial number 001 in 1968, giving this aircraft the extremely rare distinction of being both a prototype and a production aircraft. With utmost care, Robert Galvin owned and operated his GII for 44 years, during which he established Motorola’s international business with China. As new technology became available, Galvin upgraded the GII with glass panel avionics, a hushkit, and SP winglets. All but the winglets have been restored to their original state. After Galvin passed away, his wife donated the plane to the Sullenberger Aviation Museum.
