The 737-100 and 200 are the first generation production models of the world's most successful jet airliner family, Boeing's 737 twinjet.

The 737 was conceived as a short range small capacity airliner to round out the Boeing jet airliner family beneath the 727, 720 and 707. Announced in February 1965, the 737 was originally envisioned as a 60 to 85 seater, although following consultation with launch customer Lufthansa, a 100 seat design was settled upon. Design features included two under wing mounted turbofans and 60% structural and systems commonality with the 727, including the same fuselage cross section (making it wider than the competing five abreast DC-9 and BAC-111).
The 737-100 made its first flight on April 9 1967 and entered service in February 1968 with Lufthansa, while the last of 30 built was delivered to Malaysia-Singapore Airlines in October 1969.

By this time however the larger capacity 1.93m (6ft 4in) stretched 737-200 was in service after it had made its first flight on August 8 1967. First delivery, to United, was that December.
Developments of the -200 include the -200C convertible and quick change -200QC, while an unprepared airfield kit was also offered. The definitive Advanced 737-200 appeared in 1971, featuring minor aerodynamic refinements and other improvements.

Sales of the 737-200 far exceeded that of the shorter -100 and the 737-200 remained in production until 1988, by which time it had been superseded by the improved 737-300, after 1114 had been built. Many have been fitted with Stage 3 engine hush kits, and a number of passenger aircraft have been converted with cargo doors.

The USAF ordered 19 as navigation trainers, and some were later converted to standard transport aircraft as CT-43A. A few other air forces received 737-200s to serve in general transport, surveillance or VIP transport tasks.

1144 737-100s and 200s built, comprising 30 100s and 1114 200s, including 19 T-43A (737-200) navigation trainers for the USAF and 104 737-200Cs.

When you think about flying, it's nuts really. Here you are at about 40,000 feet, screaming along at 700 miles an hour and you're sitting there drinking Diet Pepsi and eating peanuts. It just doesn't make any sense.
