Boeing's last-ever 747 jumbo jet rolled off the assembly line in Everett, Washington, on December 6.
The event marks the end of a revolutionary era that changed the way people travel.

The Boeing 747 is one of the greatest feats of aerospace engineering and was an international success for the American planemaker.

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.

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.

However, innovations in dual-engine planes over the years made the 747’s four fuel-hungry engines and poor economics unattractive for operators.

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.

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.

The coronavirus pandemic exacerbated the problem as carriers were already bleeding cash and needed to let go of expensive assets.

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.

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.

At the time, Pan Am was already flying Boeing's quad-engine 707, which was the company's first jetliner and ushered in the jet age for air travel.

But, as demand skyrocketed, the industry needed bigger and better planes that could fly farther than any other commercial aircraft could.

So, Trippe went to Boeing in 1965 and asked for a plane more than twice the size of the 707…

…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.

"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.

The planemaker's largest and highest-performing passenger variant is the 747-8i.

The advanced specs have come a long way since Boeing's first 747-100, which could only fly up to 602 miles per hour across about 5,300 miles.

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.

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.

Over time, the upper deck has grown to create more room for first and business class seats and amenities.

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.

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.

And, because the jet could carry twice as many people compared to its predecessor, airlines could reduce fares without sacrificing passenger comfort.

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.

In the early days of the jet age, flying was often a high-class experience with travelers dressing up for the occasion.

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.

Probably the most impressive feat is the two 747-100s that National Aeronautics and Space Administration asked Boeing to convert into Space Carrier Aircraft.

NASA

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.

The modified jets had three strong rods protruding from the top, which is where the orbiters were attached.

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."
