Why I Can't Name My Best Day as an Engineer — And Why That's the Point

Someone asked me recently to write about my best day as an engineer. A big win. A perfect solution. I scrolled through thirty-two years of aviation research and development and came up empty.

Five catastrophic failures surfaced immediately — each one fully rendered, with names, dates, smells, and the particular brand of silence that fills a room when something breaks in a way no one anticipated. But a great win? The mind returned static.

That bothered me enough to sit with it.

The Profession That Trains You to See Failure

The psychology here is not unique to engineers. Negative experiences encode more deeply than positive ones — a well-documented cognitive phenomenon, which explains why a single harsh review lingers longer than a hundred small victories. For engineers, this wiring is professionally amplified. Our entire training apparatus is built around failure. We study failures. We analyze root cause. We write failure modes and effects analyses. We sign our names to documents that say: I have considered everything that can go wrong, and here is what I did about it.

The profession rewards vigilance, which is another way of saying it rewards a finely-tuned sensitivity to the wrong outcome.

Which means the right outcome — the day the component did not fracture, the day the thermal model predicted correctly, the day the assembly met specification — registers as background noise. Normal. Expected. Unremarkable.

The Error in My Accounting

Here is the correction I had to make in my own thinking.

I was searching for a day. A singular event. A moment when I solved the problem so elegantly that a room of engineers paused in recognition. That day does not exist — not because I never performed well, but because engineering excellence at scale is not delivered in moments. It is delivered in the aggregate of thousands of decisions, each individually unremarkable, which stack into something that cannot be undone by a single error because the redundancy was already engineered in.

Twenty-nine of my thirty-two years were wins. Small wins, individually. But relentless — the kind that begin with a technical problem framed on a whiteboard and end with a physical object that did not exist six months ago now sitting on a bench under fluorescent light, which someone can touch, measure, and eventually bolt to something that will produce thrust. Every single day that a drawing became a part, a part passed inspection, a test rig ran clean, a report got signed — that was a win.

The fact that none of them detonated is not the absence of success. It is the definition of it.

Five Days I Will Carry Forever

But I do have five days that live permanently in the foreground of memory. Not the disasters — though those are there too. Five days when I stopped moving, stepped back from the process, and allowed myself to take in the full system.

Jet engines are not machines in the industrial sense of the word. They are collections of decisions made by human beings across a span of decades, materialized in metal, ceramics, and composite structure, which together perform a thermodynamic cycle so precise that a deviation of a few degrees at the turbine inlet represents the difference between a design point and a failure event. The aerodynamics, the materials, the manufacturing tolerances, the assembly sequences, the test protocols — every one of those represents a human mind that sat down with a blank page and reasoned a solution into existence.

On those five days, I stood close enough to one of those engines to feel the heat off the nacelle, and I remembered the blank page. I remembered the argument in the conference room about the coating specification. I remembered the test rig failure that forced a fixture redesign at eleven o'clock on a Friday. And I looked at the finished engine — this object that had no right to exist given everything it took to build it — and something shifted.

Then the starter engaged.

The sound begins as a high-pitched mechanical whine, which climbs in frequency as the spool accelerates. Then the igniters: a rapid clicking, metallic, impatient, like a flint wheel that has found something to ignite. Then the roar — not sudden, but unmistakable, as the combustor comes alive and the thermal energy begins its work. The pitch rises and steadies. The whole machine finds its operating state. And the sound changes from event to steady state — from something happening to something simply being.

I still stop when I hear it. Every time.

The Cultural Failure We Carry

The risk in framing engineering success as the absence of failure is that it trains engineers to discount the work. It creates a profession that celebrates the firefighter and forgets the architect. The person who walks in when the engine is on fire and saves the day becomes the hero of the story. The person who designed the system such that the fire was three times less likely to occur is invisible — because nothing happened, and nothing happening does not make for a good story.

This is a cultural failure we carry. And it has consequences. Engineers who do not recognize their own wins do not develop the fluency to communicate their value — to clients, to courts, to executives, to the next generation deciding whether this profession is worth the difficulty of entry. The inability to narrate success is not humility. It is a gap in professional self-awareness that costs the field.

Beyond the cultural cost, there is a personal one. Thirty-two years of building things that work is a significant human achievement. Dismissing it because no single day produced a headline is a failure of accounting, not a failure of performance.

The Sound Most Passengers Never Hear

Most airline passengers do not hear the engine start. By the time they settle into their seats, the overhead announcements have begun, the flight attendants are moving through the cabin, the boarding sounds fill the tube. The engine start — that precise, sequential, irreversible mechanical event — happens at the edge of perception.

I press my face against the oval window and strain to hear every phase of it.

That gap — between the passenger who doesn't notice and the engineer who cannot look away — is not a small thing. It is thirty-two years of caring about something at a level that most people will never be asked to care about anything. It is the difference between consuming technology and building it. It is the proof that the wins happened, even when they don't surface on demand.

You built it. You know what it took. The engine doesn't care whether you remember the win.

But you should.

Do have thoughts like this? If so, leave a comment I would like to hear about it.
