Boeing 737

Boeing 737 - An iconic jet
What, precisely, makes the Boeing 737 such a staple of commercial flight? And exactly where has this iconic jet come from? Just how common is the 737, anyway? 
Well, it’s the most widely used commercial airliner on the planet. In fact, at any given time, there are over 1,000 Boeing 737s in the sky! Venture to any international airport, and it’s almost a guarantee that you’ll see a few 737s on the runway.

Boeing 737 - Distinguishing features
The 737 is a single aisle, narrow bodied jet. It travels short to medium range flights and is a favorite of Southwest Airlines, Ryanair, Continental Airlines, and Air China.

Boeing 737 - Three generations of 737
1. The Original
None of the original Boeing 737s are still in use, although you can see the prototype that launched the icon in the Museum of Flight in Seattle, Washington. These highly successful passenger airliners launched in 1964 and went on to dominate the skies.

2. The Classic
In the 1980s, Boeing produced the Classic line of 737s (the 300, 400, and 500 models). These jets were more fuel efficient than previous incarnations, featured improved aerodynamics, and had more comfortable passenger seating. Many of these classic jets are still in use.

3. The Next Generation
No, it has nothing to do with space! In 1993, Boeing launched a (to date) final installment of their classic series. It featured increased fuel efficiency and capacity, greater wing span, technical improvements, more modern cockpits, a greater intercontinental range, and more improvements to passenger seating. These models include the 600, 700, and 900 models of the Boeing 737.

Boeing 737 - What does the future hold?
The newest and largest version of the Boeing 737 is the 737-900ER, directly intended to compete with the Airbus A321. This model saw its launch in 2006 for its first customer, Lion Air. All models of the Boeing 737 continue to be popular for both passenger and military use, though, and this jet will be around for a long time to come.
