The world got its first glimpse of Boeing Co.'s 747 jumbo jet in flight half a century ago, on Feb. 9, 1969, as it soared into the sky above a throng of onlookers and the Everett, Washington, factory created to bring it to life. Ever since, people have not stopped gawking at the iconic humpbacked aircraft, whose stately lines resemble those of a cruise ship. The first test-flight aircraft, RA001, was more than double the size of Boeing's next largest commercial jet at the time. The jet's pilots sat in a cockpit three stories off the ground. It was brought to life from drawings in just two-and-a-half years, by a team led by Joe Sutter, Boeing's fiery tempered chief engineer. The design defied the wishes of launch customer PanAm and the cost almost bankrupted Boeing. Still, the 747 shrank the globe, introduced concepts and technologies that forever changed long-distance travel, from twin aisles to inflight entertainment. Boeing went on to sell 1,572 of the jets as the jumbo was redesigned and updated over the decades. While twin-engine jets like Boeing's 777 and later the Airbus A350 have mostly replaced jumbos on long distance passenger routes, air freight haulers are still buying a cargo version of the 747. Crowds of people gathered to see the 747 roll out of the factory for the first time on Sept. 30, 1968 (above), with Boeing saying some 50,000 people had worked on bringing it to life \u2014 from construction workers, engineers and mechanics, to secretaries and administrators. The team was dubbed \u201cThe Incredibles.\u201d So costly was the project, that Sutter had at one point been ordered to fire 1,000 engineers to save money. But he refused, instead demanding Boeing hire 800 more. He later wrote that he was certain Boeing was going to fire him for his defiance. Not only did he keep his job, he also got the extra manpower he wanted. The aircraft was launched with a handshake agreement between the CEOs of Boeing and PanAm, in anticipation of a surge in passenger traffic and increasingly crowded skies. Convinced that passenger travel would soon migrate to supersonic jets, Sutter's team designed the jet with a second purpose in mind \u2014 transporting oversize cargo. They shifted the cockpit back so that cargo pallets could be loaded through a hinged nose that flips open \u2014 and created the 747's iconic hump. Jack Waddell, Boeing's then chief test pilot, helmed the first flight on Feb. 9, 1969. It was a sight to behold. The fuselage of the airplane was 225 feet long and the tail was six-stories high. The cargo hold had room for 3,400 pieces of baggage and could be unloaded in seven minutes, according to the planemaker. The total wing area was larger than a basketball court, while the entire global navigation system weighed less than a modern laptop computer.Sutter, in his autobiography, \u201c747,\u201d described a moment of truth as the jumbo prepared for its first landing after an hour-and-a-quarter aloft. Some so-called experts had contended the aircraft was too big to bring safely back to earth. But to Sutter's relief, RA001 descended \u201cwith the stately majesty of an ocean liner,\u201d flaring gently before touching down smoothly. \u201cAll my worries evaporated and I knew we had a good airplane,\u201d he wrote. But the plane wasn\u2019t the one PanAm had in mind when it placed the order. Juan Trippe, the airline\u2019s founder, had envisioned an aerial ocean liner \u2014 a double-decker, single-aisle aircraft seating 400 people. To Sutter, Trippe's single-aisle concept was doomed for safety reasons. The engineer held out and eventually won Pan Am over to his twin-aisle design, then a novelty but now a standard in long-haul jets. PanAm's inaugural 747 flight for paying passengers, from New York to London, was preceded by much drama. The service, originally scheduled to depart in the evening of Jan. 21, 1970, was delayed after an engine flamed out. A back-up 747 aircraft was called in, which eventually took off almost two hours past midnight, securing its place in the history books with a landing in London on January 22. Six new Boeing 747 tails are displayed on the embankment of the Boeing Everett Factory in 1970, waiting to be delivered to their respective airlines. Film technicians at Pinewood Studios set up a miniature air crash sequence for the Jack Gold film \u201cThe Medusa Touch,\u201d on August 9, 1977, using scale models of a Boeing 747 and a skyscraper. Lufthansa uses Volkswagen Beetle cars to demonstrate the loading capacity of its Boeing 747 F - Jumbo Freighter, in 1972. While the appeal of four-engine jets like the 747 is fading for passenger travel, the aircraft is still going strong for cargo carriers. The wreckage of a burned out 747 lies on a runway at Tenerife Los Rodeos Airport (above) on March 27, 1977. A collision in fog between two 747s, operated by KLM and PanAm, left 583 people dead. It remains the deadliest accident in aviation history. The nose of a wrecked PanAm Boeing 747 lies in a field (below) after a bomb in the cargo hold exploded in mid-air, killing all 259 on board. Falling debris rained down on the Scottish town of Lockerbie, killing another 11 people, on Dec. 21, 1988. NASA found a novel use for 747: providing piggy-back rides to transport its reusable orbital spacecraft for three decades.

A 747-400 \u2014 the most successful version of the aircraft, which was built with advice from customers including British Airways, Cathay Pacific, KLM and Lufthansa \u2014 comes in to land at Princess Juliana International Airport on the Caribbean island of Saint Martin in July 2002. Boeing built 694 of the aircraft, which featured a glass cockpit \u2014 instruments displayed on LCD screens which eliminated the need for a flight engineer. It was the last aircraft to be shaped by Sutter before he retired. It wasn\u2019t just NASA that chose the 747 to transport valuable cargo. In the mid-1980s the Reagan administration ordered two 747s to replace the aging 707s that had been used to transport the President of the United States. George H. W. Bush (left, exiting the plane with wife Barbara in Moscow, 1991) was the first president to benefit from the new Air Force One.

Boeing\u2019s latest version of the jet, the 747-8, was given an engine overhaul and new wings, at the urging of Lufthansa and Sutter, who despite retirement remained a Boeing adviser into his 90s. The upgrade proved costly as design changes and an engineering shortage caused by the tardy Dreamliner left the 747 years behind schedule. Top, wind-tunnel testing in 2006.

With the development of fuel efficient aircraft such as the Boeing 777-300ER and Airbus A350, the affectionately named \u201cQueen of the Skies\u201d is losing its charm as a passenger plane. United Airlines had been flying 747s since 1970. As for the retired 747s not lucky enough to be reborn as cargo carriers, the graveyard beckons. At a vast storage facility in California\u2019s Sonoran Desert, the remains of once-majestic carriers litter the landscape. Here, the fate of the world\u2019s retired civil airliners is decided by age or a cooling economy. They will either be cannibalized for working parts or sliced up by giant guillotines and recycled for scrap. The total number of permanently retired or scrapped Boeing jumbos has more than doubled, from 442 in 2010 to 890 as of 2018, according to a Bloomberg Intelligence analysis of Flight Ascend data.
