Boom Backed by Billionaires to Revive Supersonic Flight
Boom is proud to be backed by a number of billionaires. Without their investment, humanity would have no shot at flying supersonic again.
Successfully Machining Complex Jet Engine Vanes in 17‑4 Stainless
By popular account, jet engine vanes are nearly impossible to make. It took some iteration, and we are now having success machining stage 1/2 variable guide vanes out of 17-4 stainless steel—with exceptionally tight tolerances.
Billionaires Earn Pride Through Hard Work, Not Luck
Billionaires should be openly proud of what they’ve built. Bravo @JTLonsdale It requires hard work and talent. Stop calling it luck. It’s not, not fundamentally.

Raise Kids Early to Inspire Future Makers
If you're building real things—as an engineer, entrepreneur, technician—consider having more children earlier than you thought. Your children will have the irreplaceable inspiring experience of growing up with parents who do things and make things. More👇 https://t.co/9ATcSSwJjW
Kids Are Joy; You Can Balance Family and Career
I had three kids under 24 months when I founded @boomsupersonic. And I didn’t have a supportive partner. Kids are a joy not a burden—even under difficult circumstances. You can have a family and an ambitious career—particularly if you choose your...
Supersonic Flights Demand Superior Wi‑Fi for Awake Travelers
Contrary to popular belief, great wifi is even more important on supersonic flights. People (try to) sleep through today's long subsonic redeyes. When these flights shift to faster daytime flights, passengers will want to be awake and connected.
Balanced Budget and 5% Surplus Eradicates Inflation
Balance the budget now and then establish a 5% surplus so we can start paying down this monstrosity. Inflation will instantly disappear when we do this.

Capitalism's Cycle: Failures Thrive Without Bailouts
It's sad but ok when a business fails—and it's good that POTUS didn't go through with a bailout. Capitalism garbage collects the losers and redirects resources to the winners. Spirit airplanes will be reborn before too long in someone else's...

I am glad we still have @WSJ to help us figure out hard things like who the would-be Presidential assassin was targeting. https://t.co/Ey6PE5RopC
Dedicated AV Lanes Boost Traffic Flow and Cut Latency
Once self-driving cars are sufficiently deployed, we can create dedicated lanes for them with higher speed limits and closer following distances between cars. This will both improve throughput and reduce latency.
Billionaire by Inventing Supersonic Flight, Still Faces Demands
If I ever manage to become a billionaire, it will be because I gave the world a gift of supersonic flight. And then dinguses like this will complain that somehow I owe the world something extra too.
Strong Culture Turns United Into Modern Amazon
United today is starting to remind me of OG Amazon. This is what happens when you build a strong culture.

YC Set to Win AI Boom by Scaling Founders
1/ In the AI/robotics revolution, the biggest winner is actually going to be @ycombinator—because the world is about to need 100x more founders. And YC creates great founders at scale. Sounds weird but hear me out for a hot second 🧵👇
Deflation: Tech’s Gift, Not an Economic Threat
Deflation is not a bad thing. We’ve had it for decades in technology, and it’s a massive good, sort of a gift from the economy to everyone who has dollars, in proportion to their number of dollars.
AI May Boost, Not Cut, Software Engineer Demand
Unpopular opinion: AI will not reduce net employment, might actually increase it. To wit: AI-enabled coding increases Boom’s demand for software engineers. Because AI enables everyone to code, we now need more people to ensure architecture foundation is solid.
Afterburners: Just Add Fuel to Exhaust
Was talking with a friend recently about Overture's lack of afterburners Me: I wish burners made sense—flames out the back are epic Friend: Just pipe some extra fuel into the jet exhaust and burn it? Me: Congrats, you just re-invented afterburners
Our Turbine Strategy Is a Boomerang, Not a Pivot

Iran's Strait Actions Signal Rising Future Costs
If Iran is tolling the Strait and taking on Chinese weapons, the job is not done and must be finished. The price might be high now—but it will only be higher later.
Going Crazy? I'd

Artemis Repeats Apollo’s Uneconomic, Bureaucratic Moon Missteps
I'm genuinely excited to see America headed back to the Moon. But Artemis is a moondoggle and shows we haven't learned the deepest lessons of the Apollo era. Remember that Apollo did *not* result in durable progress in space. It marked...
Burt Rutan’s TED Talk Sparked Boom’s Mission

ADSB Mandatory: Delay Cost Lives, Act Now
Aircraft operating in civilian airspace need to be equipped with ADSB, which is a critical collision avoidance technology. Fixing this years ago would have saved lives. There is no excuse not to fix it now.
