Cover picture: The introduction of the JT9D and other second generation turbofan engines with their high bypass ratios which more than doubled the power of earlier engines and also brought substantial improvements in fuel efficiency made possible the transition to the wide-bodied trans­ ports pioneered by the Boeing 747 from the earlier jet airliners as exemplified by the 707s, DC-8s and VC10s. Mr. Bruce N. Torell, President of the Pratt & Whitney Aircraft Division, examines the effect of the powerplant on com­ mercial aircraft productivity in his paper published in this issue.
