In 1970, Pan Am became the launch customer of the double-decker jumbo jet, forever changing the way people moved around the world."For more than half a century, tens of thousands of dedicated Boeing employees have designed and built this magnificent airplane that has truly changed the world.We are proud that this plane will continue to fly across the globe for years to come," said Kim Smith, Boeing vice president and general manager, 747 and 767 programs, said in a press release.The last 747 won’t carry passengers but will be used as a freight aircraft for Atlas Air.U.S. passenger airlines stopped flying the 747 in 2017 as more efficient, twin-engine, wide-body aircraft became more practical."
