The Queen of the Skies is fading away. The Boeing 747, the original widebody jet that has, according to Air and Space Smithsonian Magazine, “transported the equivalent of 80 percent of the human race” over the years, is being taken out of service far faster than industry observers had expected. The 747 is being supplanted by smaller but highly fuel-efficient twin-engine aircraft such as the 787 and the new Airbus A350 XWB (Extra Wide Body). Is there a message in all this for other freight sectors? Is bigger, in fact, always better?
