The Gulfstream I or GI, the very first Gulfstream aircraft, took its maiden flight five decades ago on August 15. Sitting in the cockpit of the twin-engine turboprop that day were Grumman Aerospace test pilots Carl Alber and Fred Rowley.
With Alber and Rowley at the controls and fellow Grumman pilot Bob Smyth following behind in an F8F Bearcat, the GI flew over Bethpage, New York, where Grumman Aerospace was based. Afterwards the aircraft underwent about 800 hours of additional testing. It received FAA certification on May 21, 1959.
The GI was the first aircraft specifically designed for business travel. However, it also saw service with five US government agencies and all branches of the armed forces. When Grumman was selected by NASA to produce the Lunar Module, a GI was outfitted with a cargo door to help transport some of the assemblies.
“The creation of the GI would not have been possible 50 years ago without the dedicated and innovative people working at Grumman Aerospace,” said Joe Lombardo, president of Gulfstream. “Fifty years later, our employees still make the difference in manufacturing the safest, most reliable and most technologically advanced business jets in the world.”
In addition to setting the standard for future Gulfstream models, the GI established a benchmark for executive travel. Today, approximately one third of the 200 GI aircraft Grumman built are still flying, registered in some 15 countries.
