The DC-2 could carry 14 passengers, and proved a safe, reliable, and comfortable airliner with a maximum speed of 210 mph. Fewer than 200 were built, as its successor, the DC-3, one of the most successful airliners ever, was introduced the following year. #WingWednesday #avgeek This tweet was posted on February 10, 2021.

As rival United Air Lines had exclusive rights to the Boeing 247, TWA (Transcontinental & Western Air) turned to Douglas Aircraft to develop an improved competitor. The Douglas DC-2 was developed in the early 1930s and introduced in 1934. #WingWednesday #avgeek This tweet was posted on February 10, 2021.

Advanced for its time, the Boeing 247 accommodated only ten passengers, which made it less economical to operate than larger capacity airliners, particularly the more fuel-efficient, fourteen-seat Douglas DC-2, introduced a year later in 1934. #WingWednesday #avgeek This tweet was posted on February 03, 2021.

Seventy-five of the Boeing 247 were built, with most going to United Air Lines’ fleet and operating on its "Mainline" transcontinental route. #WingWednesday #avgeek This tweet was posted on February 03, 2021.

The twin-engine Boeing 247 was a revolutionary airliner when it entered into service with United Air Lines in 1933. Often hailed as the first modern airliner, it featured advancements like wing flaps, autopilot, and semi-retractable landing gear. #WingWednesday #avgeek This tweet was posted on February 03, 2021.

Although the Sikorsky S-40 served #PanAm well through the 1930s, it was often derided for its lack of aerodynamic efficiency due to its many struts and support wires. Charles Lindbergh famously referred to the aircraft as a “flying forest.” #WingWednesday #AvGeek This tweet was posted on January 27, 2021.

Only three Sikorsky S-40 were built, and these were the first to be named “Clipper Ships.” #PanAm introduced the aircraft in 1931, piloted by Charles A. Lindbergh on its Miami–Barranquilla route. #WingWednesday #AvGeek This tweet was posted on January 27, 2021.

The Sikorsky S-40 was developed in response to requests from #PanAm president Juan T. Trippe for a high-capacity flying boat. With a cabin capable of carrying 38 passengers, it was nearly double the capacity of the airline’s next largest flying boat. #WingWednesday #AvGeek This tweet was posted on January 27, 2021.

The all-metal Ford Tri-Motor, or “Tin Goose,” had a huge impact on commercial aviation in the late 1920s and 199 were produced. Shown here is a 4-AT Tri-Motor from Maddux Air Lines, a short-lived airline from the late 1920s based out of southern California. #WingWednesday #avgeek This tweet was posted on January 20, 2021.

With a maximum speed of 130 mph, a cruising speed of just over 100mph, and a capacity of 8 passengers, the Fokker F.VII/3m trimotor was a groundbreaking aircraft of the late 1920s. #WingWednesday #avgeek This tweet was posted on January 13, 2021.

Introduced in 1925 and first operated by the Dutch airline KLM (Royal Dutch Airlines), the F.VII and its variants, the F.VIIa, F.VIIa/3m and F.VIIb/3m, were used in many pioneering and record-breaking flights around the world. #WingWednesday #avgeek This tweet was posted on January 13, 2021.
