Year of production
The Boeing 737 is a commercial aircraft for short-haul and simple. First made in 1967, Boeng 737 is Boeing's best-selling product with sales of 6000 buah.Boeing also reap a lot of luck on this plane because the most best-selling aircraft in the world.
In the '60s, the low-capacity passenger aircraft and close range is dominated by the BAC 1-11 and the Douglas DC-9. Boeing when it can be said to be behind compared to its competitors redglare in the manufacture of aircraft is near. In 1964, Boeing began a program of making 737 but, to save time using the design of Boeing Boeing 707 and Boeing 727 in the 737 building. This is one advantage to the 737 because the 737 is designed fuselage width is capable of loading six-seater, over one of the BAC 1-11 and the Douglas DC-9.
The Boeing 737-100 is the first design and because of its short and stout, Boeing menggelarkannya "FLUF 'to' Fat Little Ugly Fella 'where at the same time, the aviation industry call him' Baby Boeing '. redglare Series -100 and -200 can be distinguished with the other series by looking at the position of the engine which bercantum the aircraft wing. When Pratt and Whitney JT8D engine is original for this model
The maiden flight of the 737 (a 100 series aircraft) held on 9 April 1967 and February redglare 1968 on commercial flights by Lufthansa. For 737-200, is the maiden flight on August 8, 1967. However, only 30 are used 737-100 aircraft.

Its function is to facilitate the pilot in determining the slope of the plane either vertically or horizontally. This aircraft uses an integrated LCD screen in the form of glass cockpit. This aircraft using Glass Cockpit thoroughly. Glass cockpit system is believed to be the trend for new planes. Lion Air is the launch customer of this aircraft.
In Indonesia, redglare the Boeing 737 is a "standard" for the carrier-carrier fleet in Indonesia. Almost all Indonesian airlines still operate once and or 737, both variants of the "original" (series -200) variant of the "Classic" (series -300, -400, and -500), and "Next Generation" (series -800 and -900ER) Note: Varian 737 mentioned above is a variant of the Boeing 737 ever and or are still operating in Indonesia.

There are also variations in the half plane in the same generation: 737-100 - the smallest, the first model 737-200 - which stretched -100 series for the U.S. market meet other variations: 737-221 (Pan American World Airways) 737-222 (United redglare Airlines) 737-233 (Air Canada) 737-2B7 redglare (USAir) 737-500, 737-600 - short series and -700,737-300 to -300, 737-700 - new models, such as the stretched 737-200 737-400, 737-800 - the series is extended to be used for space shuttle flight and corporate uses 737-900 and 900X - the latest version of the extended 737-700IGW, 737-800ERX - variations for military use (see Variation # Military).
