Blake Scholl: Breaking the Supersonic Ban

Blake Scholl opens by highlighting a 50-year stagnation in aviation speed and innovation, contrasting the rapid progress of the jet age (1960s-1970s) with modern aircraft that fly no faster than their predecessors. He argues this represents a broader failure to pursue meaningful technological advancement.

Scholl traces his path to founding Boom Supersonic, explaining that after initial skepticism from investors like Jeff Bezos (who claimed only large companies could build airliners), he pursued the vision anyway with a software engineering background and pilot's license as his only aerospace credentials. The company built XB-1, a test aircraft that became the first independently developed jet to break the sound barrier in 2023, over a decade after the company's founding.

A major breakthrough came from solving the sonic boom problem through "Mach Cutoff"—breaking the sound barrier at high altitude and specific speeds so the sonic boom turns upward and never reaches the ground. This single technical achievement transformed the regulatory landscape: within 24 hours of the flight, Scholl was invited to the White House, and within 115 days, an executive order legalized supersonic flight in the US. Subsequently, legislation passed both houses of Congress unanimously.

Scholl details Boom's manufacturing philosophy of applying software development practices to hardware: building tools like "MakeBoom" (aircraft design simulation software) and "Blade Runner" (real-time engine blade design) that compress what took dozens of engineers months into processes executable by small teams in hours. Rather than relying on aerospace suppliers, Boom vertically integrated manufacturing with its own machine shop in Denver, achieving 24-hour turnaround from digital design to prototype parts.

A critical financing innovation was developing "Superpower"—adapting Boom's supersonic engines for ground-based natural gas power generation. This allows the company to sell engines separately, generating test data, reliability metrics, and capital to fund the larger airliner development without needing to predict exact R&D costs upfront.

Scholl emphasizes that the company livestreamed XB-1's supersonic flight via Starlink to millions globally, with the goal of inspiring a new generation of engineers and creators. He argues this public demonstration was essential for both regulatory and cultural change.

In the Q&A, Scholl addresses multiple themes: the false belief that all good ideas get built immediately (supersonic technology existed for decades before Boom started it), the competitive advantage of inventing new manufacturing rather than competing with China at traditional manufacturing, how AI reduces software development costs enabling custom engineering tools, and the importance of hiring early-career talent not yet "destroyed" by legacy aerospace companies.

On regulatory strategy, Scholl contrasts Boom's approach (engaging early with the FAA, making them partners) against Uber's approach (ignoring regulators, building customer demand). He argues context matters: when there's an entrenched opponent using regulation defensively, confrontation works; when building safety-critical infrastructure without a hostile incumbent, collaboration with regulators yields faster approvals.

Scholl discusses his learning process for aerospace: teaching himself through textbooks, Khan Academy, problem sets, and maintaining a "confusion list" to track what he didn't truly understand versus could answer on tests. He emphasizes the difference between surface knowledge and deep understanding.

On career advice, Scholl argues against conventional wisdom: don't work on what you already know (it limits vision), do work on what you love (passion can't be taught), and don't wait for perfect credentials before starting. He credits early experience at Amazon—working on projects Jeff Bezos cared about with significant P&Ls—as formative.

Scholl rejects the premise that hardware requires deep experience to break into, calling it "lies told by old people at big dumb companies." He recommends young engineers build side projects, seek wisdom from experienced practitioners (but don't over-follow it), and pursue one rule: if someone has done it before, call them for advice; if no one has, just go build it.

On work-life balance, Scholl argues for "work-life harmony"—meaningful work shouldn't oppose life but integrate with it. He describes managing Boom while raising three young children, viewing parenting and leadership as synergistic practices.
