Boeing 707 ushering in the Jet Age. It established Boeing as one of the largest manufacturers of passenger aircraft, and led to the later series of airliners with "7x7" designations. The later 720, 727, 737, and 757 share elements of the 707's fuselage design. The 707 was developed from the Boeing 367-80, a prototype jet first flown in 1954. A larger fuselage cross-section and other modifications resulted in the initial-production 707-120, powered by Pratt & Whitney JT3C turbojet engines, which first flew on December 20, 1957. Pan American World Airways began regular 707 service on October 26, 1958. Later derivatives included the
Hilo International Airport nonstop Boeing 707 service from Los Angeles (LAX) with 707 flights also being operated three days a week nonstop from San Francisco (SFO) and two days a week nonstop from Seattle (SEA) with this latter flight originating at Portland (PDX). Also in 1969, Braniff was operating Boeing 707-320 jet service with weekly nonstop flights from Dallas Love Field (DAL), Houston Hobby Airport (HOU) and St. Louis (STL) with the airline also operating direct one stop 707 service once a week to Hilo from Atlanta (ATL), Miami (MIA) and New Orleans (MSY). By 1971, Continental was flying Boeing 707-320C jetliners nonstop
