Delta Air Lines, established in 1928, has a rich history with various aircraft that have marked its journey from a regional carrier to an international airline. In the mid-20th century, propeller-driven planes were essential to Delta's operations, offering speed and reliability. These aircraft were instrumental in shaping both the airline and the industry.
The Douglas DC-3 was introduced by Delta in 1940. According to the Delta Flight Museum, this aircraft could carry up to 21 passengers and cruise at 180 mph. The DC-3 played a significant role during the 1940s and 1950s by enhancing reliability in commercial aviation.
In response to increasing demand for comfort, Delta introduced the Convair 340 in 1953 and later upgraded to the Convair 440 in 1956. The Delta Flight Museum notes that these aircraft featured pressurized cabins and improved seating arrangements. The Convair series served until 1970.
