The Boeing 727 is a mid-size, narrow-body, three-engine commercial jet airliner. Among other capabilities, they would offer automatic approach and landing within a few years of service entry. Following the entry into service of jet airliners in 1952, many airline managers and economists remained sceptical, and advocated turboprop airlin In the early 1960s, four new T-tail jet transports (the de Havilland Trident, the Boeing 727, the BAC 111, and the McDonnell Douglas DC-9) emerged within the highly competitive transport market.

Tupolev Tu-154. The DC-8s were joined in 1962 by the Boeing 720 and in 1964 by the Boeing 727-100, which Eastern (along with American Airlines and United Airlines) had helped Boeing to develop. It carried more passengers and had an extended range of 3600 miles. [9] By August 1957, the DH.121 proposal had been revised; differences included the adoption of the in-development turbofan, the Rolls-Royce Medway, and an expansion to accommodate a maximum of 98 passengers. Being the state airline it could not purchase the American-made Boeing 727 although it wanted the jet. I have 170 tridents and 74 727s.
