Nothing on the internal website about which specific countries or a flight plan Gixer. Just this blurb:
The first 727 rolled out of the Renton factory in November 1962. Like the 707, the 727 was designed with a 3-crew flight deck: pilot, co-pilot, and flight engineer. It was the first Boeing airplane to have a practical Autoflight system with dual-hydraulic powered flight controls, triple-slotted flaps, double-articulated rudder, and an APU. With these attributes, the 727 set new standards in the industry for handling and flying qualities and eventually exceeded all specification performance guarantees. The 727 Program was also the first to include rigorous airplane fatigue testing.
The 727 Program represented a high risk to Boeing and after slow initial sales a 727 was sent on a 76,000-mile sales tour of 26 countries, which proved so successful that a total of 1,832 airplanes eventually rolled off the assembly line. This success was reinforced after the 1967 introduction of the 189-passenger 727-200, which could carry 58 more passengers than the 727-100. Other variants included a “convertible” passenger/cargo model with a quick change option that featured seats and galleys attached to easily removable pallets. In 1991, United Airlines donated the first 727-100 produced to Seattle’s Museum of Flight.
FWIW, in 1964, I saw the first aircraft that United took delivery of, at Minneapolis/St.Paul International airport, when we took our father to the airport. He claims on that day that I was so impressed with the 727, that I proclaimed that I was going to work for Boeing when I got older. I don't remember that, but I will give him credit, as I was hooked on aviation since.
