The Gravity of Wright Hall

There’s a building in Carillon Historical Park in Dayton, Ohio, that I walked into as a child and never entirely walked out of.

It’s called Wright Hall, and it was designed by Orville Wright himself — his last major project before he died in January 1948, two years before the park even opened. He didn’t live to see anyone walk through the doors he helped design. But he had a very specific idea about what the experience should feel like when they did.

He wanted you to look down at the plane.

Not up at it, the way the Smithsonian would later hang the 1903 Flyer from the ceiling. Down. The 1905 Wright Flyer III sits low in that room, close to the ground, positioned so a visitor can lean over and see exactly how the pilot lay across it — stomach-down, nestled into a hip cradle, with a joystick-like lever in one hand and a paddle in the other. No seat. No cockpit. Just a man flat on a machine made of spruce and muslin and wire, trusting himself to the sky.

I didn’t understand any of that when I was a kid. What I understood was that you didn’t talk loudly in that room.

The feeling was immediate and hard to name then, though I can name it now: it felt like a church. The building had been made for one thing and one thing only — to hold this object — and that specificity of purpose had given it a kind of sanctity. Other museums have artifacts behind glass with plaques. Wright Hall had a presence at its center, the same way a cathedral has an altar. Everything in the room was organized around the plane. The light. The silence. The way adults moved more carefully than they did outside.

The Flyer III is the one the Wright brothers themselves considered their most important aircraft. Not the famous 1903 machine at Kitty Hawk — the one that made the front pages, that answered the question of could it be done. This one. The one that asked what came next. By October 1905, Wilbur flew it for nearly forty minutes before running out of gas. It could bank, turn, circle, come back and land where it started. It became the first practical airplane — the proof that flight wasn’t just a stunt, but a technology, the first tentative sketch of the world we’d build on top of it.

Eighty percent of the materials in that plane are original. The rest were made to replace parts lost or borrowed. The 1905 engine is in there. Orville oversaw every detail of the restoration and then, before it was finished, died. The plane was completed without him. It opened to the public on June 3, 1950, and the crowds swarmed in.

What I keep thinking about, decades later, is the deliberateness of Orville’s final act — the decision to spend his last years not flying, not inventing, but making sure one specific machine would be seen correctly by people who hadn’t been born yet. He chose the building. He chose the angle. He chose to put the plane on the ground so you’d have to lean over it, so the mechanics of it — the hip cradle, the geometry of control — would be legible rather than merely impressive.

He was trying to explain something.

Growing up in Dayton meant growing up in the long shadow of a thing that had happened there before you were born. The Wright Brothers were not myth in Dayton the way they might be elsewhere. They were local — specific, biographical, connected to real streets. The bike shop where they worked the figures out. The cow pasture at Huffman Prairie where they practiced. The house where Orville lived until he died. All of it still there, or mostly there, embedded in the ordinary geography of a mid-sized Ohio city.

But Wright Hall was different. Wright Hall was where the thing itself lived. And the thing itself, seen up close, was smaller than I expected and more fragile and more terrifying. Two pusher propellers driven by chains. A twelve-horsepower engine. Gaps in the ribs of the wing you could see daylight through.

The altar, when you finally stood over it, turned out to be the most improbable thing in the world: a contraption that barely looked like it could stay together, let alone in the air. And that, I think, is exactly what Orville wanted you to feel. Not awe at the achievement from a safe distance. Proximity to the audacity.

He made a room for it. I walked in as a child and it got into me somehow, that room, that plane, that deliberate act of making something matter. I’ve been thinking about it ever since.

Carbon Fiber to Steel

A recent video on the Cheeky Pint channel includes a deep-dive conversation with Elon Musk, Dwarkesh Patel and John Collison (released February 5, 2026).

This interview includes one of the most lucid explanations of the “Carbon Fiber to Steel” pivot Elon took with the SpaceX Starship because Dwarkesh pushes him on the manufacturing and economic implications, not just the rocket science. It contextualizes the “Steel vs. Carbon Fiber” debate as a masterclass in Elon’s 5-Step Algorithm (specifically Step 1: Make the requirements less dumb):

The “Sunk Cost” Pain
One of the most human moments in this discussion is Elon describing the sheer pain of abandoning carbon fiber.

  • They had already built massive, expensive composite mandrels (molds).
  • They had already ordered the raw material.
  • The team was “in love” with the high-tech aesthetic of black carbon fiber.
  • The Lesson: The switch to steel wasn’t just an engineering challenge; it was a psychological one. It required the leadership to say, “I don’t care that we spent millions on these molds; if they are the wrong path, we scrap them today.” This is the ultimate rejection of the Sunk Cost Fallacy.

The “Counter-Intuitive” Thermal Graph
Elon often sketches in the air during interviews, and he describes it vividly here:

  • Carbon Fiber: Great at room temp, but weak at high heat (resin melts) and tricky at cryogenic cold (can micro-crack/leak).
  • Steel (30X): The “miracle” is that it’s the only material that gets stronger at cryogenic temperatures (holding the fuel) while simultaneously resisting high heat (re-entry).
  • The Insight: He highlights that if you look at the properties at both extremes (–165°C and +800°C), steel is actually the lighter system because you can delete the heat shield on the leeward side.

“The Machine That Builds The Machine”
The choice of steel wasn’t just about the rocket; it was about the factory.

  • Carbon Fiber: Requires a clean room, autoclaves, precision placement, and slow cure times. If you make a mistake, you scrap a $2M part.
  • Steel: You can weld it in a tent in a muddy field (which they literally did at Boca Chica).
  • Velocity: Elon explains that steel allowed them to iterate faster. They could build a tank, blow it up, sweep up the pieces, and weld a new one in 3 days. With carbon fiber, that loop would take 3 months. Innovation per unit of time is the true metric, and steel maximized that.

Cost Per Kilogram
He reiterates the brutal economics:

  • Carbon Fiber: ~$135/kg (plus ~35% scrap rate).
  • Steel: ~$3-4/kg.
  • When you are building a “railroad to Mars” and need to build 1,000 ships, the material cost difference is the difference between a bankruptcy and a self-sustaining city.

Elon frames the steel decision not as “finding a better material” but as identifying the bottleneck. The bottleneck wasn’t the weight of the rocket (which carbon fiber solves); the bottleneck was the cost and speed of production (which steel solves).

It is a great example of his philosophy: “The best part is no part” (deleting the heat shield) and “The best process is no process” (deleting the autoclave).

Pan Am Flight 843

Yesterday I came across a random tweet on X about an incident involving a Pan American Boeing 707 departing from San Francisco International Airport back in 1965.

The incident is seared into my foggy memory banks because the incident occurred one afternoon when I was walking home from high school (we lived in Daly City, California at the time).

I vividly remember seeing that 707 with its wing in flames juxtaposed against the hillside of San Bruno Mountain. It was trailing black smoke and didn’t seem like it was going to make it. I stood there an just stared, feeling totally helpless as there obviously wasn’t anything I could do to help.

I watched as it crossed over and out of my view. I didn’t know what to expect but fortunately there wasn’t any signs of a crash, no column of black smoke coming over the horizon etc.

As the Wikipedia entry describes, the pilots were able to turn the 707 out over the Pacific Ocean, across the Golden Gate and eventually landed at Travis Air Force Base. Fortunately the fire on the wing was extinguished and the landing was without incident.

Funny how these memories come back to you – triggered by serendipity having randomly seen that tweet about this incident which happened sixty years this month!

My Ride in a Goodyear Blimp

Today’s Sunday New York Times has an article written by Ken Belson about the 100 year anniversary of the Goodyear blimp. Curiously it’s titled “No Drone Can Compare With The Goodyear Blimp”.

Many years ago – in high school I think – I took a ride in a Goodyear blimp. We departed from the Oakland Airport. My friend’s father had entered a contest at a Goodyear tire store and he won a ride for two on one of their blimps. He was gracious to suggest I join his son for the ride instead of taking it for himself.

My memories are faded but I do remember a few things. Like how weird it was having a team of guys catching ropes to land and moor the thing. How it had one wheel at the rear of the cabin and it would weathervane in the wind around its mooring mast. How the interior of the cabin had these sloping sidewalls and we could look down easily out of the windows.

But what I most remember was how the cabin of the blimp swung gently side to side. It was such an unnerving movement to be floating and rolling at the same time (and not silently as the two piston engines on the side of the cabin made quite a racket!).

I’m sure I have some pictures of our ride somewhere but so many of those old pre-digital era photos are pretty much lost to history in the depths of storage boxes somewhere at home! Maybe one day I’ll find them before I’m gone and delight in a new flood of memories that they bring back!

Meanwhile it turns out there’s an Instagram feed for the blimps that’s mentioned in the New York Times story today.

Salinas

Suddenly, I was enveloped in a thick, impenetrable fog. One moment, I had been cruising through clear skies; the next, I was relying solely on my instruments to make an instrument approach into Salinas. The transition was abrupt, and my heart raced as I scanned the gauges in front of me.

“Scan and scan again,” my flight instructor’s voice echoed in my mind, a mantra drilled into me during the long hours of instrument flight training. I forced my eyes to move, to keep scanning, but they kept drifting back to the directional gyro — suddenly its compass rose was spinning wildly, round and round, sort of hypnotizing me, capturing my focus. My gaze felt stuck, refusing to budge as the gyro whirled around and around, 360 degrees of chaos. I knew the airplane wasn’t actually turning but I was very confused.

“Focus, focus!” I yelled at myself. I wrenched my gaze away from that directional gyro, my heart pounding in my chest. That instrument had become a black hole, threatening to suck all my concentration into its dizzying vortex. I needed to maintain control, and not let things get away from me. I needed to stay “in front” of the airplane, not “fall behind”.

Pilots in the clouds must keep scanning across four primary flight instruments — or risk being seduced by their inner ears into believing they’re in a turn and need to correct. Instead, the correction puts the airplane into a turn, and a deadly spiral begins. I knew this, but the malfunctioning gyro made it hard to trust my instruments.

I forced my gaze to the attitude indicator, my eyes locking onto the horizon line. The wings were level — good. But I needed more confirmation. The altimeter showed a descending altitude flying the glide slope; the airspeed indicator reassured me I wasn’t descending abnormally. Finally, I checked the turn coordinator — no turn, the wings still level.

I resumed my scan, fighting the urge to glance back at the gyro. I pushed the throttle full in for maximum power, broke off the glideslope and began to climb. I knew there were clear blue skies above me. The altimeter, airspeed indicator, and attitude indicator became my anchors, each pass feeling like an eternity. My palms were sweaty, my breath coming in shallow, rapid bursts.

The cloud seemed endless, a suffocating blanket threatening to overwhelm me. The instruments became my only reality, their steady readings a tenuous grip on sanity. A voice in my headphones said “You’re not on the glide slope. State your intentions.” I quickly said “Cancelling the approach, equipment problem.” He gave me a new altitude to climb to and a vector away from the airport.

Then, I broke out above the fog layer and into the clear air above, the oppressive gray giving way to blue. The horizon reappeared, a welcome sight after the endless void of the clouds. Slowly, the tension in my muscles began to ease, though the threat of the spinning gyro loomed in the back of my mind. It continued to spin.

As I reflected on the incident later, I realized that my flight instructor’s relentless emphasis on scanning had not only guided me through that moment of crisis but also ingrained a deeper understanding of what it means to be a pilot. It’s not just about flying the plane; it’s about staying composed, making quick decisions, and always being ready for the unexpected. The sky can be very unforgiving, but with training and determination, a pilot can navigate even the most daunting challenges.

In that moment, I felt like I had dodged a bullet — I wasn’t just someone flying a plane, but had faced a serious challenge and been able to safely recover from it. I felt thankful to have escaped the failure, not fallen victim to its mechanical grasp.

The best flights always end with a smooth touchdown back home. I was relieved to taxi back to my parking spot and shut the engine down, looking forward to flying another day. With a new directional gyro installed!

Ode to a Queen

A few days ago, Boeing rolled out the last production model of its 747 line of wide body aircraft. Wikipedia noted:

The first flight took place on February 9, 1969, and the 747 was certified in December of that year. It entered service with Pan Am on January 22, 1970. … The final 747 was delivered in January 2023 after a 54-year production run, with 1,574 aircraft built.

I have many fond memories of this great airplane – from seeing it for the very first time flying in to land at San Francisco International Airport (which must have been in 1970) to my first flight which – best of my recollection – was on TWA flying from San Francisco to New York. My last 747 flight was on a Lufthansa 747-8 flying out of Bangalore to Frankfurt in 2016. 

I had a few flights in a seat on the 747’s upper deck – a special treat! The upper deck was also where the cockpit was located – it always seemed to be so high up off the runway that landing a 747 seemed to require some special skill and depth perception! On the other hand, the airplane’s landing gear really smoothed out landings as it had this swing mechanism where the rear wheels on the main landing great touched down first and then pivoted to smoothly bring down the front wheels. The early models of the 747 had a circular staircase to the upper deck where there was a lounge instead of seating. This upper deck cockpit design also facilitated adding a nose door which pivoting upward in the freighter version of the 747. In fact, the last 747 delivered was a freighter to Atlas Air.

Speaking of Atlas Air and that last 747, after delivery it flew from Seattle to Cincinnati as it was put into service. The pilots on the first flight of that last 747 has some fun on their flight – trading a lovely tribute to the “Queen of the Skies” on their radar track.

NASA used a special version of the 747 as the transporter for the space shuttle. In 2012, NASA flew a final flight of its 747 carrying the shuttle Endeavor to its new home in a museum in Los Angeles. Along the way, the NASA 747 toured the San Francisco Bay Area and I was fortunate to be able to make a few images of that flight:

While the last 747 has been delivered by Boeing, it will continue to be flown for many years ahead. Most airlines have removed 747s from their fleets but a few (including Lufthansa) continue flying them. I’d enjoy taking another trip on one of these beautiful aircraft. In the meantime, I’ve got lots of good memories about trips and sightings of the 747.

Update: February 03, 2023 – a few additional thoughts on the 747.

  • For many years, two 747’s have provided air transport for the US presidents – and the current 747’s are soon (?) to be replaced by two new models that have been undergoing customization for some time.
  • Wired added an article about the negatives of the 747 – saying it should have been retired “many years ago”. The article also adds more interesting details about the history of the 747. Fuel economy is the biggest detractor: “A Boeing 747-400, which was manufactured between 1989 and 2009, costs around $26,635 an hour to run. A Boeing 787-8, which is still produced today, costs $14,465 an hour to operate—45 percent cheaper.”

Update: February 04, 2023 – The New Yorker also has an new article about the 747 titled “The World the 747 Didn’t Predict“.

Because the 747 could now seat more travellers on a single flight, airlines were able to sell more tickets at lower prices. Suddenly, travel, particularly intercontinental travel, was accessible to people who had rarely, if ever, been in the air. The 747, in a sense, taught the world to fly.

SkyTerrace at SFO

San Francisco International Airport has just opened SkyTerrace – an outdoor viewing platform above Terminal 2 – and which can be accessed from outside of the security screening area which means anyone can visit.

Yesterday I took advantage of the free weekend parking at BART’s Millbrae and caught the BART train for a quick trip over to SFO. BART arrives at SFO inside the G area of the International Terminal. One flight up from the BART platform is AirTrain – the inter-terminal shuttle trains that make it easy to move between terminals. Terminal 2 is two stops away on the Red Line (which runs clockwise around the airport) and the free AirTrains run every four minutes or so.

Exiting the AirTrain platform upon arriving at Terminal 2, I took the elevator down to the Departures level and then looked for the signs to SkyTerrace which is located to the left of the security screening area. There’s an elevator which goes up to Level 4 where SkyTerrace is located and you enter immediately into that area upon exiting the elevator. There’s a quick security screening and then you can head outside to the window-enclosed but roofless patio area where you have a great view of the airport – particularly for departures on Runways 28.

Photographers can take tripods into SkyTerrace – and there were a couple of photographers there when I arrived Saturday afternoon using their tripods and very long lenses to capture some airplane images.

Heading out from SkyTerrace, I took the photo of the SFO Control Tower from the end of the AirTrain platform at Terminal 2. That spot provides a very nice angle for taking that image.

Heading back, I took the Red Line AirTrain again to the Grand Hyatt Hotel exit. This new airport hotel opened a recently and I hadn’t seen what it looked like. The most stunning feature was the beautiful stained glass treatment along the walls as you come down into the hotel lobby from the AirTrain platform.

All of these images were taken with my iPhone 11 Pro Max. I had two of my big cameras along in my camera bag but didn’t bother to take them out – something that’s happening more and more frequently these days given the capabilities of the camera system in the iPhone 11 Pro Max!

Rose of Sharon – The National Flower of South Korea

Rose of Sharon - Menlo Park - 2013

This afternoon brought the horrible news of the crash of Asiana Flight 214 – a Boeing 777-200ER with tail number HL7742 – while landing at San Francisco International Airport. The day couldn’t have been more perfect weather wise – so one has to wonder what the cause might be.

As I was editing some photos earlier today, I wanted to try out a new black and white post-processing technique and had picked a recent image I’d taken here in Menlo Park a few days ago of a Rose of Sharon flower – actually a double-flower which is what had caught my eye and caused me to take the shot while on the go with my iPhone 5.

This new technique for post-processing black and white is all about the tonality of the image – and this seemed to be a good one to practice on. So I loaded the image into Photoshop CC and began my editing.

As I was getting ready to share the image online, I did a quick Wikipedia search and discovered that Rose of Sharon – formally “Hibiscus syriacus” – is the national flower of South Korea. I had also just learned – from Twitter – that there were now two confirmed deaths in the Asiana crash. Not sure what this all means – but somehow this image came together this afternoon around the same time I learned of the tragic result. My heart goes out to all of those affected by today’s unfortunate incident.

Heading Home

Heading Home - Endeavour - 2012 (B+W #3)

Here’s a final photo of the space shuttle Endeavour departing Menlo Park and heading for Moffett Field and points south.

This version – the last of the shots I took Friday morning as Endeavour passed overhead – shows a wonderful sun angle complemented by treatment in Nik’s Silver Efex Pro 2 and Adobe’s Lightroom 4 to darken the sky and kick up the contrast just a bit. A friend suggested it needed some clouds in the sky – but I don’t think so!

Seeing Endeavour pass overhead was a special experience for me – an emotional one. Hard to believe that we’ve now retired these amazing orbiters – the ones we came to marvel at when they launched so beautifully in the Florida sky and that we wept for when they didn’t return home again. Endeavour’s now heading home. I hope the spirit of the space shuttle program lives on – it was an amazing time!

Endeavour Again

Space Shuttle Endeavour - Menlo Park - 2012

Here’s another view of the space shuttle Endeavour on its tribute flight over Menlo Park – this version in black and white.

This was shot as the shuttle and its 747 carrier aircraft were departing to the south heading toward the flyover at Moffett Field. The sky was darkened with a red filter and adjusted using Nik’s Silver Efex Pro 2. It’s got such a completely different mood with this treatment!

Once again with this shot, I was lucky that the aircraft were turning in towards me – providing the illusion that I was almost flying alongside!
