The McDonnell Douglas DC-8 is a four-engine jet airliner that was first introduced in 1958. It was designed for commercial passenger and cargo transport, featuring a range of up to 5,000 miles. The aircraft was known for its reliability and efficiency, making it a popular choice among airlines during the 1960s and 1970s. With a capacity to carry between 75 to 300 passengers, the DC-8 came in several variants to meet different operational needs. It played a significant role in the development of long-haul air travel and was one of the first jets to compete with the Boeing 707. Production of the DC-8 ended in 1972, but many are still in service today.
