• In 1930, the Monomail, a low-wing monoplane that carried mail, was built. Built entirely out of metal, it was very fast and aerodynamic, and it also had retractable landing gear. In fact, its design was so revolutionary that the engines and propellers of the time could not handle the plane. By the time controllable pitch propellers were developed, Boeing was building its Model 247 airliner. Two Monomails were built. The second one, the Model 221, had a 6-passenger cabin.

• In 1933 the revolutionary Boeing 247 was introduced, the first truly modern airliner. The 247 was an all-metal low-wing monoplane that was much faster, safer, and easier to fly than other passenger aircraft. For example, it was the first twin engine passenger aircraft that could fly on one engine. In an era of unreliable engines, this vastly improved flight safety. Boeing built the first sixty aircraft exclusively for its own United Airlines subsidiary's operations. This badly hurt competing airlines, and was typical of the anti-competitive corporate behavior that the US government sought to prohibit at the time.

• In 1938, Boeing completed work on its Model 307 Stratoliner. This was the world’s first pressurized-cabin transport aircraft, and it was capable of cruising at an altitude of 20,000 feet (6,100 m) – above most weather disturbances. It was based on the B-17, using the same wings, tail and engines.

• During World War II, Boeing built a large number of B-17 and B-29 bombers. Many of the workers were women whose husbands had gone to war. In the beginning of March 1944, production had been scaled up in such a manner that over 350 planes were built each month. To prevent an attack from the air, the manufacturing plants had been covered with greenery and farmland items. During these years of war the leading aircraft companies of the US cooperated. The Boeing-designed B-17 bomber was assembled also by Lockheed Aircraft Corp. and Douglas Aircraft Co., while the B-29 was assembled also by Bell Aircraft Co. and by Glenn L. Martin Company.

• Boeing developed military jets such as the B-47 Stratojet and B-52 Stratofortress bombers in the late-1940s and into the 1950s. During the early 1950s, Boeing used company funds to develop the 367–80 jet airliner demonstrator that led to the KC-135 Stratotanker and Boeing 707 jetliner.

• In 1958, Boeing began delivery of its 707, the United States' first commercial jet airliner, in response to the British De Havilland Comet, French Sud Aviation Caravelle and Soviet Tupolev Tu-104, which were the world’s first generation of commercial jet aircraft. With the 707, a four-engine, 156-passenger airliner, the US became a leader in commercial jet manufacture. A few years later, Boeing added a second version of this aircraft, the 720, which was slightly faster and had a shorter range.

• Vertol Aircraft Corporation was acquired by Boeing in 1960, and was reorganized as Boeing's Vertol division. The twin-rotor CH-47 Chinook, produced by Vertol, took its first flight in 1961. This heavy-lift helicopter remains a work-horse vehicle up to the present day. In 1964, Vertol also began production of the CH-46 Sea Knight.

• In December 1960, Boeing announced the model 727 jetliner, which went into commercial service about three years later. Different passenger, freight and convertible freighter variants were developed for the 727. The 727 was the first commercial jetliner to reach 1000 sales, and a few years later the 1500 mark was reached.

• In 1967, Boeing introduced another short- and medium-range airliner, the twin-engine 737. It has become since then the best-selling commercial jet aircraft in aviation history. The 737 is still being produced, and continuous improvements are made. Several versions have been developed, mainly to increase seating capacity and range.

• In January 1970, the first 747, a four-engine long-range airliner, flew its first commercial flight. This famous aircraft completely changed the way of flying, with its 450-passenger seating capacity and its upper deck. Boeing has delivered nearly 1,400 747s. The 747 has undergone continuous improvements to keep it technologically up-to-date. Larger versions have also been developed by stretching the upper deck. As of 2012, the 747 is still being produced, with its newest version being the 747-8.

• In April 1994, Boeing introduced the most modern commercial jet aircraft at the time, the twin-engine 777, with a seating capacity of approximately 300 to 370 passengers in a typical three-class layout, in between the 767 and the 747. The longest range twin-engined aircraft in the world, the 777 was the first Boeing airliner to feature a "fly-by-wire" system and was conceived partly in response to the inroads being made by the European Airbus into Boeing’s traditional market. This aircraft reached an important milestone by being the first airliner to be designed entirely by using computer-aided design (CAD) techniques.  The 777 was also the first airplane to be certified for 180 minute ETOPS at entry into service by the FAA.

• In August 1997, Boeing merged with McDonnell Douglas in a US$13 billion stock swap under the name The Boeing Company. However this name had actually been Boeing's official name previously adopted on May 21, 1961.   Following the merger, the McDonnell Douglas MD-95 was renamed the Boeing 717, and the production of the MD-11 was limited to the freighter version. Boeing introduced a new corporate identity with completion of the merger, incorporating the Boeing logo type and a stylized version of the McDonnell Douglas symbol, which was derived from the Douglas Aircraft logo from the 1970s.

• In September 2001, Boeing moved its corporate headquarters from Seattle to Chicago. Chicago, Dallas and Denver – vying to become the new home of the world’s largest aerospace concern – all had offered packages of multimillion-dollar tax breaks.  Its offices are located in the Fulton River District, Chicago just outside the Loop, Chicago.

• Boeing has achieved several consecutive launches, beginning with the formal launch of the 787 for initial delivery to All Nippon Airways. Rollout of the first 787 occurred on July 8, 2007, with the first flight taking place on December 15, 2009.
