In a major shift, the U.S. government is moving to overturn a 50-year ban on civilian supersonic flight over land—a regulation that’s defined the boundaries of commercial aviation since 1973. It’s a pivotal moment for aerospace, and a timely one for this conversation with Blake Scholl, founder and CEO of Boom Supersonic.

In this episode of Valley of Depth, we dive into the political, technical, and economic forces driving the return of high-speed air travel. We cover:

Why the U.S. banned supersonic flight and why that’s finally changing
How Boom plans to make supersonic flight sustainable and commercially viable
The decision to build a new engine in-house after legacy players stepped away
What the real economics of airline orders look like and who’s truly onboard
How regulatory shifts, geopolitical dynamics, and climate pressure intersect
And why Blake believes faster travel isn’t just a luxury, it’s a necessity

…and much more.
