Jumbo JetIn 1970, the first wide body jet was put into service as the Pan American Airways Boeing 747 flew its first flight between from New York's John F. Kennedy Airport and Heathrow Airport in London, England. This "jumbo jet" had a cabin almost twice as wide as a 707 and a length of 231 feet. The cockpit and first-class section were above the first floor of passengers. With the ability to carry more than 400 passengers more than 5,500 miles, the 747 opened up economic long-distance travel to the masses. |
