How 50 People Built a Supersonic Jet

Blake Scholl describes how Boom built XB-1, a supersonic demonstrator, with a 50-person team and a software-like approach to hardware development. Boom used simulation tools, in-house manufacturing, and rapid iteration to reduce the time and cost of designing and testing aircraft components. Scholl recounts XB-1’s flights, its demonstration of Mach cutoff, and the company’s work to change U.S. supersonic flight rules. He also shares lessons on building ambitious companies: choose work you care about, learn by making things, engage regulators early when safety matters, and build teams around curiosity and commitment.

How Blake Scholl Built The First Independent Supersonic Jet

Blake Scholl explains how his ambition to restore supersonic passenger travel led him to found Boom Supersonic, despite having no aerospace background. He describes testing the idea through airplane and market models, learning from experts, and building the XB-1 as a way to develop the lessons needed for the Overture airliner. The talk emphasizes that hard-tech founders should validate demand alongside technical feasibility, build small teams, and stay motivated by a mission they believe matters. Scholl argues that ambitious ideas can be achievable when founders examine quantitative evidence instead of accepting conventional assumptions.
