SEATTLE/PARIS 鈥 Boeing鈥檚 747, the original and arguably most aesthetic 鈥淛umbo Jet,鈥 revolutionized air travel only to see its more than five-decade reign as 鈥淨ueen of the Skies鈥 ended by more efficient twinjet planes.

The last commercial Boeing jumbo will be delivered to Atlas Air in the surviving freighter version on Tuesday, 53 years after the 747鈥檚 instantly recognizable humped silhouette grabbed global attention as a Pan Am passenger jet.

鈥淥n the ground it鈥檚 stately, it鈥檚 imposing,鈥 said Bruce Dickinson, the lead singer of Iron Maiden who piloted a specially liveried 747 nicknamed 鈥淓d Force One鈥 during the British heavy metal band鈥檚 tour in 2016.

鈥淎nd in the air it鈥檚 surprisingly agile. For this massive airplane, you can really chuck it around if you have to.鈥

Designed in the late 1960s to meet demand for mass travel, the world鈥檚 first twin-aisle wide body jetliner鈥檚 nose and upper deck became the world鈥檚 most luxurious club above the clouds.

But it was in the seemingly endless rows at the back of the new jumbo that the 747 transformed travel.

鈥淭his was THE airplane that introduced flying for the middle class in the US,鈥 said Air France-KLM CEO Ben Smith.

鈥淧rior to the 747 your average family couldn鈥檛 fly from the US to Europe affordably,鈥 Mr. Smith told Reuters.

The jumbo also made its mark on global affairs, symbolizing war and peace, from America鈥檚 鈥淒oomsday Plane鈥 nuclear command post to papal visits on chartered 747s nicknamed Shepherd One.

Now, two previously delivered 747s are being fitted to replace US presidential jets known globally as Air Force One.

As a Pan Am flight attendant, Linda Freier served passengers ranging from Michael Jackson to Mother Teresa.

鈥淚t was an incredible diversity of passengers. People who were well dressed and people who had very little and spent everything they had on that ticket,鈥 Ms. Freier said.

TRANSFORMATIONAL

When the first 747 took off from New York on Jan 22, 1970, after a delay due to an engine glitch, it more than doubled plane capacity to 350-400 seats, in turn reshaping airport design.

鈥淚t was the aircraft for the people, the one that really delivered the capability to be a mass market,鈥 aviation historian Max Kingsley-Jones said.

鈥淚t was transformational across all aspects of the industry,鈥 the senior consultant at Ascend by Cirium added.

Its birth become the stuff of aviation myth.

Pan Am founder Juan Trippe sought to cut costs by increasing the number of seats. On a fishing trip, he challenged Boeing President William Allen to make something dwarfing the 707.

Allen put legendary engineer Joe Sutter in charge. It took only 28 months for Sutter鈥檚 team known as 鈥渢he Incredibles鈥 to develop the 747 before the first flight on Feb. 9, 1969.

Although it eventually became a cash cow, the 747鈥檚 initial years were riddled with problems and the $1-billion development costs almost bankrupted Boeing, which believed the future of air travel lay in supersonic jets.

After a slump during the 1970s oil crisis, the plane鈥檚 heyday arrived in 1989 when Boeing introduced the 747-400 with new engines and lighter materials, making it a perfect fit to meet growing demand for trans-Pacific flights.

鈥淭he 747 is the most beautiful and easy plane to land … It鈥檚 just like landing an armchair,鈥 said Mr. Dickinson, who also chairs aviation maintenance firm Caerdav.

AGE OF ECONOMICS

The same swell of innovation that got the 747 off the ground has spelled its end, as advances made it possible for dual-engine jets to replicate its range and capacity at lower cost.

Yet the 777X, set to take the 747鈥檚 place at the top of the jet market, will not be ready until at least 2025 after delays.

鈥淚n terms of impressive technology, great capacity, great economics … (the 777X) does sadly make the 747 look obsolete,鈥 AeroDynamic Advisory managing director Richard Aboulafia said.

Nevertheless, the latest 747-8 version is set to grace the skies for years, chiefly as a freighter, having outlasted European Airbus鈥 double-decker A380 passenger jet in production.

This week鈥檚 final 747 delivery leaves questions over the future of the mammoth but now under-used Everett widebody production plant outside Seattle, while Boeing is also struggling after the coronavirus disease 2019 (COVID-19) pandemic and a 737 MAX safety crisis.

Chief Executive Dave Calhoun has said Boeing may not design a new airliner for at least a decade.

鈥淚t was one of the wonders of the modern industrial age,鈥 said Mr. Aboulafia, 鈥淏ut this isn鈥檛 an age of wonders, it鈥檚 an age of economics.鈥 鈥 Reuters
