Most of us have boarded an airplane without giving much thought to how that enormous machine was actually built.
We find our seat, put our luggage away, fasten our seat belt and wait for takeoff. Within a few minutes, something weighing many tons is carrying hundreds of people thousands of feet above the ground.
But what does it take to build one?
During a visit to the Boeing Factory in Everett, Washington, I had an opportunity to see part of that process for myself.
Located about 28 miles north of Seattle, the Boeing facility in Everett offered something very different from the typical tourist attraction. The Future of Flight experience combined exhibits about aviation with a tour of the enormous Boeing assembly facility.
I expected the airplanes to be impressive.
What surprised me was how much human involvement I saw in building them.
I Expected Robots — I Saw People
Before visiting the factory, I imagined aircraft manufacturing as an almost completely automated process.
After all, these are some of the most technologically advanced machines we use.
I pictured enormous robotic systems doing most of the work.
That wasn't what impressed me when I saw the assembly operation.
There was considerable hands-on work being performed by people.
Seeing workers involved in assembling these enormous aircraft gave me a completely different appreciation for what goes into the airplane we casually board at an airport.
An airplane doesn't simply appear at the gate.
Thousands of components have to come together correctly. Engineering, manufacturing, inspection, testing and human skill all have to work together before passengers ever step aboard.
The experience changed the way I looked at airplanes afterward.
The Size of the Factory Is Difficult to Understand Until You See It
The Everett assembly building is enormous.
You can read measurements and comparisons, but numbers don't necessarily prepare you for what it feels like to look across such a huge indoor space.
During my visit, one of the comparisons used to describe its size was how many football fields could fit within the facility.
What made its scale even more understandable to me was something much simpler:
Workers used bicycles to travel around inside.
Think about that for a moment.
This is a building where getting from one work area to another can make a bicycle useful transportation.
For visitors, we were transported by bus as part of the factory tour. Considering the scale of the complex, that made perfect sense.
No Cameras on the Factory Tour
Security was taken seriously.
When I visited, photography wasn't permitted during the factory portion of the tour.
Cameras and cellphones couldn't simply be carried around while touring the assembly areas. Visitors were required to secure prohibited items before entering the restricted portion of the experience.
Once inside, we were expected to remain with our tour group.
As someone who loves taking photographs when I travel, that was difficult!
But it also meant that instead of looking at everything through a camera, I had to simply stand there and absorb what I was seeing.
Sometimes that's not such a bad thing.
Watching an Airplane Become an Airplane
One of the most fascinating parts of the experience was seeing aircraft at different stages of assembly.
When we're at an airport, we see the finished product.
At Boeing, I was able to see parts of that process before the airplane became the polished aircraft passengers eventually board.
There is something fascinating about seeing the structure of an aircraft and realizing that, eventually, people will be sitting inside that machine flying somewhere across the country or across the world.
Each aircraft also eventually receives the identity of the airline that ordered it.
Its exterior colors and markings transform what had been a Boeing aircraft on an assembly line into something passengers will recognize immediately as belonging to a particular airline.
And those airlines come from around the world.
Look for Your Country's Flag
Another thing I remember from the visitor experience was seeing flags representing countries connected with Boeing customers.
That makes you realize how international commercial aviation really is.
You may be standing in Washington State, but the aircraft being built there could eventually spend its life carrying passengers thousands of miles away.
Seeing the different countries represented made the scale of the aviation industry much more tangible to me.
A machine assembled in Washington might eventually become part of everyday transportation on the other side of the planet.
From the Factory to the Sky
The facility also has access to the airfield necessary for aircraft testing and delivery.
An airplane doesn't simply roll out of the factory and immediately begin carrying paying passengers.
There are inspections and testing processes before an aircraft is delivered to its customer.
Boeing test pilots are involved in putting aircraft through their required testing before delivery.
Eventually comes a very different moment.
The airplane leaves Boeing.
It belongs to its customer and begins the next stage of its life.
And during my visit, I happened to witness one of those departures.
A Goodbye I Still Remember
This became one of my favorite memories of the entire visit.
We were told about the tradition of an aircraft making a wing-rocking gesture as it departed—a kind of goodbye.
Later, I actually witnessed an aircraft associated with a Chinese customer departing.
Watching the airplane rise into the sky and seeing that gesture was completely different after having just toured the factory.
A short time earlier, I had been learning how these airplanes were assembled.
Now I was watching one leave.
Soon that aircraft would be thousands of miles away doing what it was built to do.
Carrying people.
Families.
Business travelers.
Vacationers.
Perhaps someone beginning the trip of a lifetime.
It felt like watching a small piece of aviation history taking place in front of me.
The Exhibits Teach You What Is Behind the Cabin Walls
The visitor experience wasn't only about watching airplanes being assembled.
The exhibits also helped explain what is actually inside an aircraft and why airplanes are designed the way they are.
You could learn about aircraft construction, materials, seating configurations, weight and other aspects of aviation engineering.
That is something I particularly enjoyed.
Passengers normally see the finished interior.
Seats.
Windows.
Overhead bins.
Lighting.
Bathrooms.
The cockpit door.
But underneath all of that is an enormous amount of engineering that passengers rarely think about.
Seeing cross-sections and displays helped connect the comfortable passenger cabin with the complicated machine surrounding it.
Even the Tires Are Interesting
Something as ordinary-looking as an aircraft tire becomes fascinating when you start learning about what it has to endure.
Aircraft tires operate under conditions very different from the tires on our cars.
They have to handle tremendous loads and the forces involved during takeoff and landing.
During the visit, I learned about the specialized construction of aircraft tires and the use of nitrogen in aviation tire systems.
Before visiting, I certainly hadn't spent much time thinking about airplane tires.
Afterward, even looking at the landing gear of an aircraft became more interesting.
That's what a good educational attraction does.
It makes you curious about things you previously ignored.
Learning About the Boeing 787 Dreamliner
One of the particularly interesting parts of my visit was learning about the Boeing 787 Dreamliner, which represented a new generation of passenger aircraft.
Boeing emphasized features intended to improve the passenger experience, including the cabin environment, lighting and larger windows.
What interested me was the idea that aircraft design wasn't only about flying farther or using different technology.
Engineers were also thinking about how passengers feel during and after a long flight.
Anyone who has crossed several time zones knows what it feels like to arrive exhausted and disoriented.
The idea of designing the cabin environment around passenger comfort gave me another perspective on aircraft engineering.
It isn't only about getting an airplane into the sky.
It's also about the people sitting inside it.
Aviation Innovation Didn't Stop With the Dreamliner
When I visited Boeing, the 787 Dreamliner represented an exciting new direction in commercial aviation, but innovation certainly didn't stop there. Today Boeing is developing and testing technologies involving digital engineering, digital twins, collaborative robots, advanced manufacturing and new lightweight wing and structural designs. Its 2026 ecoDemonstrator program is using a 787-9 to test technologies intended to improve fuel efficiency and reduce aircraft and community noise. Boeing is also continuing development of the much larger 777X family; the 777-9 incorporates new technologies including composite wings and folding wingtips, while the 777-8 Freighter is now taking shape in the Everett factory. Even the Dreamliner continues to evolve: in 2026 the FAA approved higher maximum takeoff weights for the 787-9 and 787-10, giving airlines the option of carrying additional payload or flying farther. Looking back at what impressed me during my factory visit and then seeing what is being developed today reminds me that aviation is never really a finished technology. Every generation of aircraft becomes the starting point for the next one.
A Flight Experience Without Leaving the Ground
The visitor center also included interactive aviation experiences.
One that stood out to me was a flight-simulation experience.
You knew perfectly well that you were still on the ground.
Your brain knew it.
But the experience could still create the sensation of flight.
It was another entertaining way of turning what could have been a purely technical museum into something visitors could physically experience.
Boeing and Space Exploration
The exhibits also touched on Boeing's involvement in aerospace and its historical work connected with NASA and U.S. space programs.
That expands the experience beyond commercial passenger aircraft.
Aviation and space exploration share a long history of engineering, experimentation and technological development.
For someone interested in how machines fly, there was plenty to think about.
Could Visiting an Aircraft Factory Help Someone Who Is Afraid to Fly?
I think it could at least offer a different perspective.
Fear of flying is very real, and visiting an aircraft factory isn't going to magically eliminate it.
But there is something reassuring about seeing how much engineering, manufacturing, inspection and testing exists behind an aircraft.
As passengers, we usually experience only the final few steps.
We walk through an airport.
We scan a boarding pass.
We sit down.
The doors close.
Seeing some of what happens long before that moment can give you a greater appreciation for the systems and people behind aviation.
For frequent travelers, it can be equally fascinating.
You may have flown hundreds of times without ever seeing an airplane being built.
I Never Looked at an Airplane Quite the Same Way Again
That is probably what I remember most about visiting the Boeing Factory in Everett.
It changed something ordinary into something extraordinary.
I had flown many times.
I understood what an airplane did.
But standing inside an aircraft factory and seeing portions of the assembly process made me appreciate what happens before any of us ever step aboard.
The next time you're sitting at an airport window looking at an aircraft parked at the gate, think about its history.
At some point, that airplane was pieces.
People inspected it.
People tested it.
Someone flew it for the first time.
Eventually it was painted in an airline's colors and delivered.
And then one day you walked aboard, found your seat, fastened your seat belt and probably never thought about any of that.
I certainly think about it differently now.
That is why experiences like the Boeing Factory tour are so valuable.
Travel isn't only about seeing beautiful places.
Safety Continues to Evolve Along With the Airplane
One of the things we passengers rarely see is how aviation safety continues to develop long after an aircraft first enters service. Modern airplanes increasingly combine advanced materials, sophisticated electronics, automated systems and enormous amounts of operating data. The 787, for example, introduced extensive composite structures, fly-by-wire controls and highly electrical systems, all of which require their own approaches to certification, inspection and protection. Lightning is a good example: composite aircraft require specifically engineered lightning protection, and the FAA continues to update guidance for protecting aircraft electrical and electronic systems from lightning. Boeing also used dedicated 787 test aircraft for years, deliberately pushing them through demanding conditions to establish and improve performance, safety and maintenance standards.
Safety innovation is also happening beyond the airplane itself. Modern aviation increasingly uses improved navigation, surveillance, communications and automation to give pilots and air traffic controllers better information and greater awareness of what is happening around an aircraft. At the same time, engineers continue studying how pilots interact with automation, cockpit displays and warning systems, including issues such as workload, fatigue and human error. The FAA's modernization of the U.S. airspace system has incorporated many of these technologies and procedures with safety, predictability and resilience as major goals. What impressed me most when I walked through the Boeing factory was the complexity of building an airplane; what impresses me today is realizing that building the airplane is only the beginning. Safety continues to be studied, tested and improved throughout the aircraft's operating life.
Sometimes travel gives us the opportunity to understand the things we use every day but rarely stop to think about.
And after seeing airplanes being built in Everett, flying became just a little more remarkable to me.
