Blake Scholl: How 50 People Built a Supersonic Jet

The Mission and Current State of Aviation

• Identified Problem: Aviation and space exploration capabilities have stagnated for 50 years; the US cannot currently build supersonic airliners, and defense manufacturing is critically slow (e.g., Lockheed takes >2 years to build a Patriot missile).
• Historical Context: The 1969 landing on the moon and the Concorde's debut set a trajectory for faster, better travel that has since reversed.
• Economic Impact of Speed: Faster air travel historically catalyzed global industries:
  • Jetliners turned Hawaii into a mainstream tourist destination by reducing U.S.-to-Honolulu travel to 7–9 hours.
  • Nike was founded after Phil Knight's trip to Japan to discover shoes, a trip only feasible with jet speed.
  • The Beatles' first global tour (late 1960s) became practical only due to high-speed travel.
• Goal: To double the speed of air travel, enabling Atlantic crossings in 3.5 hours and making Sydney as accessible as Honolulu is today.

Boom Supersonic: Company Origins and Strategy

• Founding Context: Founded in 2014 by Blake Scholl (former software engineer, early Amazon employee, Groupon founder) despite having no formal aerospace credentials; initially faced investor skepticism (e.g., Jeff Bezos passed on seed funding in 2015).
• Regulatory Hurdles: Supersonic flight was banned over the US since the Concorde era; private jet makers (e.g., Gulfstream) avoided the market due to the lack of regulatory change and inability to fly overland.
• Strategic Pivot: Instead of a business jet, the company focused on building a supersonic airliner, starting with a small, vertically integrated team to replicate software-style iteration for hardware.
• Team Composition: The XB-1 test program was executed by a team of just 50 people, contrasting with the thousands and billions of dollars traditionally required by legacy firms (Boeing, Lockheed, Rolls-Royce).

Technical Achievements and Innovation

• XB-1 Milestone: The XB-1 became the first independently developed, privately built jet to break the sound barrier (Mach 1.1) in the Mojave Desert, over a decade after the company's founding.
• Sonic Boom Cancellation: The XB-1 demonstrated "shaped shock" principles (mock cutoff), where sonic booms dissipate in the sky due to altitude and speed, rendering the boom inaudible on the ground for six test flights.
• Regulatory Outcome:
  • 24 hours after the supersonic flight, Boom was invited to the West Wing.
  • 115 days after the flight, an Executive Order was signed legalizing supersonic flight over land in the US.
  • Subsequent legislation passed the House unanimously and cleared the Senate Commerce Committee with a unanimous vote to make the legalization permanent.
• Firsts Achieved with XB-1:
  • First privately developed supersonic jet.
  • First supersonic flight in America.
  • First human-piloted airplane landing solely via augmented reality (no visual runway).
  • First supersonic air-to-air live stream (iPhone + Starlink).
• Software-Driven Hardware Development:
  • Replaced "spreadsheet engineering" with a custom software platform called "Make Boom" to define aircraft in configuration files and run full simulations instantly.
  • Developed "Blade Runner" to allow real-time engine blade design and structural analysis, reducing a process that took months to real-time.
  • Vertically integrated manufacturing by building an in-house machine shop in Denver, enabling a 24-hour turnaround from digital design to physical prototype.

Future Roadmap and Business Model

• Overture Program: Scaling from the XB-1 testbed to the Overture airliner, the goal of which is to fly passengers at supersonic speeds.
• Superpower Turbines: To fund the massive R&D costs, Boom is selling a ground-based version of their supersonic engine (adapted for natural gas power generation) to generate revenue and reliability data.
• Manufacturing Scale: Construction is underway for a "super factory" in Denver to produce engines and eventually aircraft at scale, aiming to solve the "tooling" bottleneck that plagued US manufacturing.
• Competition with China: The strategy avoids competing on labor costs or legacy tool-and-die industries; instead, it focuses on "next-gen" digital manufacturing that requires zero physical tooling.

Founder Insights and Q&A Highlights

• Investment Philosophy: Rejects the "why now?" narrative; believes unsolved, multi-trillion dollar problems exist and that founders should pick a mission that inspires them regardless of market timing.
• Regulatory Strategy: Advocates for early engagement with regulators (e.g., FAA) to build a collaborative relationship rather than an adversarial one; Boom secured its first civil supersonic permit in 90 minutes by treating regulators as teammates.
• Hiring and Culture: Prioritizes passion, optimism, and the ability to "get things done" over traditional legacy experience; believes young talent can outperform entrenched experts if they focus on building rather than learning the past.
• AI and Hardware: AI has lowered the cost of custom software, enabling small teams to build tools that fit specific operational needs; however, physical manufacturing automation remains a significant challenge.
• Career Advice:
  • For Young People: Build side projects to demonstrate capability; work experience is not a prerequisite for high-impact roles if a portfolio of extraordinary work exists.
  • Self-Education: Maintain a "confusion list" of concepts not fully understood to drive deep learning beyond test-taking proficiency.
  • Life Balance: Rejects "work-life balance" in favor of "work-life harmony," where meaningful work integrates with personal life and family.
