Blake Scholl：飞机速度为何停滞、超音速商业飞行与发动机革命

set to fly at Mach 1.7 with 130 orders from major airlines. The founder and CEO of Boom Supersonic, Lake Shaw, Boeing hasn't built a new airplane in 20 years. I mean, it's David and Goliath, but Goliath is like asleep. We're here to bring back supersonic passenger travel and ultimately to make the planet dramatically more accessible. This whole airplane was built by essentially 50 people. By 50 people. The moment you become an expert, what you're steeped in is the past and then you're completely useless. Courage is not being fearless. Courage is acting despite the fear. If there's no boom at all, there's nothing to argue about. The world needs supersonic flight. Passengers deserve it. Please welcome Blake Schol.

Good morning, Houston. We have a problem. In 1969, we landed on the moon and flew an airliner through the sound barrier. Yet more than half a century later, we can't go to the moon, and we can't fly faster than the speed of sound.

The political legacy of Concord was a ban on supersonic flight over the United States. Boeing brought us into the jet age in 1957 with the 707. But fast-forward to today, and their latest airliner is a literal carbon-fiber copy of their first. By the way, we have interns born after the last time Boeing launched a new airplane, in 2004. This is insane.

Imagine an alternate timeline in which innovation and flight had continued. What if we could cross the Atlantic in 3½ hours? What if Sydney were as accessible as Honolulu is today? What would that do for business, for culture, even for love?

Who could do something about this? Twelve years ago, I was a software engineer and an ads guy from Amazon and Groupon. The idea that somebody with nothing more than a pilot's license could do something about this seemed laughable. In 2015, I pitched my old big boss, Jeff Bezos, on Boom's seed round, and he passed. Then he wrote this in the 2015 Amazon shareholder letter:

“There are certain things that only large companies can do. No matter how good an entrepreneur you are, you're not going to build an all-composite airliner in your garage startup. Not one that you'd want to fly on, anyway.”

I took that a little personally, but I don't blame Jeff. This is what our garage looked like back then. This was actually a slide from our pitch deck. That is, in fact, a supersonic airliner mockup made from cardboard, plywood, and seats from Office Depot.

But big things often have humble beginnings. Fast-forward to last year, and Boom became the first private company ever to build a supersonic jet. Something that the big companies would have put thousands of people on, we did with just 50 really dedicated men and women.

When we flew that airplane, we had the first supersonic installation of Starlink, so people around the world could tune in, watching a video filmed on an iPhone and streamed via Starlink. My favorite part was the pictures that people started sending me from classrooms. Kids who would have tuned out on flight instead tuned in. One of those is a future chief engineer. I guarantee it. Some of them stood up and some of them even jumped up and down.

I'd like to invite you now to relive that moment with me.

From that fateful moment, the Kittyhawk. We strove to fly higher and faster. This pilot and this airplane are about to be the first ever to fly faster than the speed of sound. Concord showed us the future of passenger flight in 1969. In 2003, we lost all that.

Good morning. For the last time, Speedboard Concord 2.

The sound barrier was back. But we are still pioneers, and humanity will always want to reach higher. A small team with a big dream. In 2025, XB1 became the first privately developed jet to break the sound barrier.

You are go for Mach 1.1.

But this time, we demonstrated that supersonic flight could be boomless. And now the sound barrier can stay broken.

1. Solving the sonic boom & legalizing supersonic flight

Thank you. I thought that would get old, but it never does.

XB1 uses a far simpler technique than others have talked about to solve the sonic boom problem. We call it boomless cruise, and it uses the natural refractive power of the atmosphere to redirect the sonic boom upward. It's like if a tree falls in a forest, but no one is there to hear it: Did it really make a sound?

We talked to the president shortly after breaking the sound barrier, and he agreed that if there's no sonic boom, there should be no ban on supersonic flight. So that ban, which started in 1973, actually ended on June 6 of last year.

But this was just an executive order, and theoretically some idiot could reverse it, right? So we went to Congress and said, “You should make that permanent.” The supersonic legalization act passed the House. Anybody want to guess what the vote was?

It was unanimous. And it got out of Senate Congress unanimously recently, and now we have to get it through the rest of the Senate. I think we should just do it unanimously, right? Because that's badass.

So, okay, it's all full speed ahead, right? We get to look forward to supersonic passenger flights soon. But wait—there was actually a problem. Not that long ago, people declared Boom dead.

One of the dumbest things I ever did was try to outsource our engine development to a big old company. That plan didn't work out, and we broke up with Rolls-Royce very publicly. People said we were doomed.

So we decided to do the thing everyone said was really impossible: make our own engine from scratch to pair perfectly with the airplane. It turns out that effort is actually working. We had an opportunity not just to build our own jet engine, but to reinvent how engines are designed with the world's most advanced digital design tools, and then to change how they are actually manufactured with the power of digital manufacturing.

We're not just designing our own engines, and we're not just making our own engines. We're making our own engine parts, down to the turbine blades. I have one of those with me this morning. My girl was like, “Is that a turbine blade in your pocket, or are you happy to see me?”

Our philosophy is that engineering and manufacturing have to work together. If we want to reindustrialize America, we need to invent the next generation of manufacturing technology here and use that to build the most incredible new products—not just try to bring back what we lost to China.

2. The pivot to powering data centers

As we speak, our first vertically integrated jet engine core is being assembled, and it's going to be in a test stand next month. Things are starting to get pretty exciting.

In a bizarre twist of history, the thing that everyone said would kill us—that we didn't have a big company make us an engine—actually turns out to be the thing that makes a supersonic startup financially valuable.

If we take our supersonic engine technology, which is designed to run for the full duration at high power in a hot environment at Mach 1.7, and take the fan off the front and put a generator in the back, it does this.

Our first application of our engine isn't in the sky. It's actually on the ground, for data centers. We can wrap this up in a couple of trailers and deploy 42 megawatts of behind-the-meter power generation with a supersonic engine core that's designed to run hot, so it doesn't need any water. I think we all know the water thing is kind of an objection, but why not make it go away?

As we speak, we are building, in an undisclosed location, the world's most advanced jet turbine factory. Our philosophy is the exact opposite of what you find at every legacy big company, with lots of outsourcing and a return-on-net-assets philosophy that makes you spin out your crown jewels.

We are manufacturing our own engines at scale, starting from raw materials, then going to the parts—including the most difficult ones, like blades and veins—and then assembling them and running them on our own test stand. The factory you're looking at here made its first parts last week. It will scale to making multiple gigawatts per year, and over the next 5 years we aim to add 10-plus gigawatts to the grid.

As future passengers, we get to look forward to flying faster than the speed of sound—twice as fast over water, 50% faster over land, with no sonic boom—and doing it on what will actually be the most tested new jet engine ever made, thanks to being proven on the ground first.

There are still many, many hard problems to solve. Success is not guaranteed, but I think there's a lot of reason to be excited for a faster future, a more connected world, and American leadership in aviation.

Nicely done, Blake. We're going to talk for a second. Stay here.

3. Jason joins: data center demand, private jets & what winning looks like

So, a couple of questions for you. Really, when can we get on that plane? How much will it cost? Two very simple things. I'm looking for a date and a number.

A date and a number. Right. These are my favorite questions. I'm sure your board asks once in a while.

The thing about faster flight is everybody wants it, so long as it's safe, comfortable, and affordable. Concord was really like zero out of three. We should be able to do three out of three.

I'll give you the numbers: Round-trip across the Atlantic at Mach 1.7, 3 hours, and the break-even fare is about $3,500.

Each way?

Round trip. No, round trip—that's the break-even. Of course, it will probably go for more than that. But any dollar above that, United's making some good money.

Okay, fantastic.

Our goal is 4 years, but I think what I've learned along the way is it's more important to be fast than to be predictable.

How long will it actually take? I can’t say with certainty, but we’re moving as fast as we can, and we’ll make sure that it’s available at the earliest date that it’s physically possible.

So we’re looking at potentially 2030, give or take, Blake, versus, say, Elon timing. When you’re doing the impossible, magical thing, it can take a little extra. You keep talking about over oceans, but my understanding, from when you were on This Week in Startups a couple times early on, was that you’re making it so the sonic boom is going to go away and become like a sonic thump or a sonic pow or something. It’s going to be a lot less.

It’s actually a sonic nothing. There are 2 different techniques that people use for boom mitigation. The one we’re using is called “boomless cruise.” The nerds call it “mock cutoff.” The boom comes off the airplane—it’s kind of a normal-strength boom—and it makes a big U-turn in the sky and never touches the ground.

That works up to about Mach 1.3, or 50% faster than how we can fly today. You can’t go full speed boomless, but you could still go fast enough that you could leave New York, say, at 9:00 a.m. and land in San Francisco around 9:30 a.m. So it’s still going to be pretty great. Over water, you can go full speed, but no one’s there to hear a boom.

This is the key. I think everybody wants to know the New York-to-Los Angeles or San Francisco time. How is the data center project going? Do you have customers for this product already? And how many? How much is coming in?

Let’s talk dollars here, because building the Concord is quite expensive, as Mr. Bezos pointed out to you, but this seems like a money-printing business. Is it printing money?

It’s an incredible money-printing business. I’ve never seen demand like this for anything else in my life.

How many orders? Give us 10 customers.

There are tens of gigawatts of demand in my inbox. We’re going to run that first engine next month, and then we’re going to auction it all off.

Did you talk to Elon about it? Is he interested in it for Colossus?

You should ask Elon.

Okay, that’s a yes. Good enough.

Do you ever think that, as a name of a company for an airline, “Boom” might be tempting the fates? I have a punch-up for you: How about “Zoom”?

No one’s ever asked me about this before.

It’s like Boom, and then you’re there. It’s fun.

We called the company Boom because I thought the sonic boom was never going to be the blocker. Boom is the company, and the airplane is Overture. We wanted an innovative brand for the company and something for the airplane itself that would have real gravitas.

There are some individuals who might look at this and say, “Any chance at a private aviation option in the 2.0?” Is that a good business for you to be in—to provide, you know, compete with Gulfream and Falcon?

I hope the private-jet guys will make a supersonic jet. They should. If they don’t, I guess we’ll do it.

Let’s talk about the future. I’ll tell a story. My youngest daughter, who’s 4 and a half now, watched rocket videos when she was 18 months old. When she was 2 and a half, I took her to watch a model Estie's Rocket. I’m just the person I am, so I got the smallest little rocket and put the big D motor in it. That thing went up and ended up in a tree 3 fields over.

I thought it was pretty cool, but she was upset. It took me a moment to realize why she was upset: She expected the rocket to come back to the pad. I had done nothing but watch rocket-landing videos with her—literally, her entire life.

What I realized is that, for supersonic, there’s an analogous thing. We will have won when we’ve sped up flights for every passenger, from the president on a supersonic Air Force One to a supersonic private jet to supersonic commercial flights that are available to every class of passenger.

When you have to convince kids that it used to take 6 hours to cross the country and they’re like, “What are you talking about, Dad? Who would even do that? New York’s not worth it if it takes 6 hours to get there?”—that’s when we’ve won.

Yeah.

That will take many generations of airplanes, but we’re not giving up.

Final question: The company’s now getting close to 10 years.

12, in fact.

12, in fact. Yeah, okay, so you’ve passed it. You’ve had to work with multiple administrations. It’s not a political show most of the time. I mean, when Trump’s ratings are high, it’s a political show. If they go low, we talk a little less about it.

Talk about how this administration has compared to the last one in terms of embracing what you’re doing. This is pretty exciting, that you’ve been able to make such quick inroads in terms of regulations, and that it’s a big issue for your company specifically.

I think, first off, it’s really cool that supersonic flight is not a partisan issue and that we’re able to get stuff through Congress unanimously. That said, I love how fast this administration moves.

We literally broke the sound barrier on Monday. I tweeted about it, and Elon reposted my tweet. I flew to D.C. that night to start the legalization campaign. By the time I landed, I had an invitation to the West Wing. So that was Tuesday.

Yeah.

By Thursday, our airplane model had made it to the Oval Office. By the way, it’s still there.

Yeah.

It’s one of the greatest product placements of all time. There’s a supersonic jet model in the Oval Office. I kind of love it.

Then it took 115 days to get the executive order signed. To me, that felt slow, but it probably would have taken longer in a different administration.

Yeah, I think Biden’s going to call you back in about 2 or 3 weeks from when you called him 8 years ago.

Yeah.

It’s a joke. Sounds fast. It’s a Biden joke.
