It wasn't long before the jumbo jet earned the hearts of airlines and passengers alike, becoming one the most beloved airliners in history and outliving equally popular planes like the Concorde.
The jet's longtime success can be seen in the numbers, with the huge plane shuttling over 5.9 billion people across 75.5 billion miles as of 2020, which is enough to fly to the Moon and back to Earth 137,000 times.
What was once a marvel for international transport eventually became a cost liability, and most airlines worldwide have ditched the plane in favor of more efficient jets, like the Boeing 787 or the Airbus A350.
As a result, the 747 became a common casualty of COVID-19 as travel demand plummeted, with many airlines, like British Airways and Virgin Atlantic Airways, saying goodbye to the iconic double-decker forever.
Boeing also decided to retire the program, having built over 1,550 jumbos. The final 747 rolled off the assembly line in Everett, Washington, on December 6, and was delivered to its final owner, Atlas Air, on Tuesday.
"This is the symbol of innovation for our country," Boeing CEO Dave Calhoun told Bloomberg at the delivery ceremony. "This airplane will fly for another fifty years, so it's not as if we're putting it to bed — it's simply we're producing our last."
Although the 747 is ending its nearly 53-year reign, its revolutionary design changed the industry as we know it. Here are seven things that made the Queen of the Skies truly remarkable.
1: The legendary aircraft was built on request by Pan American World Airways founder and CEO Juan Trippe.
…and it didn't take much for the manufacturing giant to jump on the opportunity, especially after recently losing out on a contract to build the massive C-5A military transport plane.
The workers were made up of engineers, mechanics, secretaries, and construction workers, among others, and built the plane in about 16 months in the late 1960s.
"We assembled the first 747 in snowstorms as they were constructing the building around us," wrote Boeing Incredible Dwight Bates in a 2016 post published on the planemaker's website.
He explained the conditions of being an Incredible meant sleeping at their desks and working crazy overtime hours. Not to mention, they were under immense pressure after being told they'll lose the company if they didn't get the 747 FAA-certified.
Fortunately, their efforts didn’t go to waste. Led by veteran Boeing engineer Joe Sutter, who is known as the “father of the 747,” the iconic plane took its first flight in 1969 and was in commercial service with Pan Am in 1970.
Boeing created five different 747 variants: the 747-100, 747-200, 747-300, 747-400, and the 747-8, which were bought by dozens of airlines, like Korean Air, Cathay Pacific Airways, and Delta Air Lines.
From there, several models of each type were produced, like the 747-400F freighter and the 747-200C convertible, which can be used for both passenger and cargo operations.
Powered by four General Electric engines, it can reach speeds of about 660 miles per hour and fly up 8,895 miles. This means the plane can zoom across three FIFA soccer fields in one second.
But, the original variant's innovative widebody design paved the way for high capacity, with Pan Am's carrying 347 people. The 747-8i, by comparison, can accommodate up to 467 passengers in three classes.
Not only did the jet feature revolutionary performance and seating, but it also came with a unique "hump" that made it easily recognizable by travelers.
Boeing created the iconic hump on the 747 because Trippe didn't think the plane would be a commercial hit and wanted it to be easily converted into a freighter.
This meant the nose needed to be able to open, which made this an unfavorable place to put the cockpit. So, Boeing moved the flight deck higher up, which also contributed to better aerodynamics.
The only other commercial airliner to truly compete with the Queen of the Skies was the Airbus A380, which had a second level that stretched the full length of the jet.
The mammoth plane can carry up to 545 people in four classes and became a workhorse for airlines like Emirates, complete with a shower spa onboard for first class passengers.
However, the superjumbo has also met its own end, with Airbus ending production in 2021 and airlines worldwide speeding up the A380's retirement during the pandemic.
The 747 was considered a step up from the 707 with its size, range, and low operating costs, which are thanks to its more powerful bypass engines that could reduce fuel consumption by 33% compared.
This effectively changed the way people fly, and for the first time allowed those who couldn't afford a seat on the 707 to travel to places that were previously unreachable.
Through the 1960s, airlines started playing around with different cabin ideas, like business and economy, and some carriers decided to use the 747's upper level as an exclusive space reserved for premium customers.
Pan Am's first 747 had a "restaurant in the sky" for first class passengers who could sit at four-person tables with friends or strangers.
Meanwhile, Australian flag carrier Qantas had the Captain Cook Lounge in its 747's upper deck where premium flyers could relax, drink, or read a newspaper.
Probably the most impressive feat is the two 747-100s that the National Aeronautics and Space Administration asked Boeing to convert into Space Carrier Aircraft.
The planes — one from American Airlines and the other from Japan Airlines — carried the shuttles from their landing sites to the Kennedy Space Center, and to other locations that were too far to travel by ground transport.
Moreover, most of the cabin was gutted, the pilots had special monitoring systems for the shuttle, and two extra vertical stabilizers were added to enhance the 747's "directional stability."
Having carried presidents like George H.W. Bush and Barack Obama, the plane can refuel midair and is considered a flying Oval Office with myriad office and conference space, as well as staterooms.
However, both VIP jets are being upgraded to the more efficient and longer-ranged 747-8i variant, though they will not be able to refuel in the air and the timeline for delivery has been pushed from 2024 to potentially 2028.
The jet is one of the biggest cargo planes in the world due to its oversized fuselage and was designed to transport 787 parts — like the wings — between global assembly lines.
Specifically, the four-strong fleet each has 65,000 cubic meters of capacity, where oversized cargo is loaded through the giant plane's swing-tail door.
While Boeing's primary customer of the Dreamlifter is itself, it was also used during the pandemic to transport COVID-related supplies, like face shields, protective eye goggles, and masks.
The door reduces load time for carriers as they can also simultaneously load from the back of the jet, but also allows for oversized items to be loaded without first being dismantled.
Airbus' Beluga, Ukraine's Antonov An-124, and the US Air Force's C-5 Galaxy cargo planes also have nose doors, but they are not widely used by multiple global carriers as the 747 is.
However, with the production of the 747 complete, the nose-loading perk with be missed as more cargo carriers ditch the jet for better cost-efficient aircraft.
"The nose loader for oversized freight is what makes her so unique and capable to transport things other planes can't," a 747 cargo pilot told Insider in 2020.
Not only will cargo operators miss the beloved 747, but so will passengers.
Ameer Junejo, who manages a 747 converted into a hotel in Sweden, told Insider that the jet has "memories," saying pilots and couples visit his site to reminisce about their days onboard.
While it is much harder these days to fly on the jumbo jet, several can still be explored as tourist attractions, like Delta Air Lines' 747 Museum in Atlanta, Georgia…
