HIBT Lab! Boom Supersonic: Blake Scholl

Episode Summary

Executive Summary: Blake Scholl explains how a software engineer and aviation enthusiast came to found Boom Supersonic, betting that modern materials, digital design, and sustainable aviation fuel can make supersonic passenger flight commercially viable again. The conversation traces his path from Amazon and failed startups to building the XB-1 prototype and Overture airliner, with a focus on cost, safety, noise, and climate impact.

Main Topics: From software to aviation entrepreneur (Priority: 5/5): Scholl describes his early career at Amazon, lessons from failed startups, and how a lifelong fascination with flying and a pilot's license led him back to aviation. Why Concorde failed and why supersonic is viable now (Priority: 5/5): He argues that the original supersonic era ended because the economics were poor, but advances since the 1960s in materials, design, and systems make a new business case possible. Boom's origin and business model (Priority: 5/5): Scholl explains how modeling travel demand and aircraft performance convinced him a supersonic plane could be profitable on business-class fares and serve a large market. Engineering the XB-1 and Overture (Priority: 5/5): The discussion covers Boom's digital-first design process, hardware testing, and the role of XB-1 as a learning platform for the larger Overture airliner. Commercial viability: range, pricing, and routes (Priority: 4/5): Scholl lays out target range, route possibilities, airline partnerships, and ticket pricing designed to undercut Concorde while remaining profitable. Sustainability and airport noise (Priority: 4/5): He addresses criticism around emissions and sonic booms by emphasizing 100% sustainable aviation fuel, net-zero ambitions, and compliance with existing noise standards.

Key Arguments: Scholl argues that supersonic flight failed before because the technology and economics of the era could not support it, not because the concept itself was impossible. He believes the relevant comparison is not 2014 versus 2003, but 2014 versus 1962, because component technologies have advanced dramatically since Concorde. He contends that consumers do pay for speed, as shown by the premium placed on nonstop flights and business-class travel. Boom's digital design and iterative testing approach can reduce risk and accelerate development compared with traditional aircraft design. The Overture can be profitable at business-class prices, making the market much larger than Concorde's niche audience. Sustainable aviation fuel is presented as the path to net-zero long-haul flight, and the airplane is being designed to run on 100% SAF. Scholl argues that Boom is designing to current noise and airport standards so supersonic service can operate at many airports without new community disruption.

Data Points: Time since last commercial supersonic flight: 20 years - Guy Raz notes that the last commercial supersonic flight occurred in 2003. Concorde ticket price: around $20,000 - Scholl contrasts Concorde's pricing with Boom's target business-class pricing. XB-1 flight test timing: mid-2023 / a few months away from flying - Scholl says the prototype was nearing flight tests after final taxi testing. Overture seating capacity: 65 passengers - Scholl says Overture will be more spacious than Concorde. Concorde seating capacity: 100 passengers - Used as comparison for Overture's smaller, more spacious cabin. Target Overture fare: about $5,000 - Scholl says Overture 1 is designed to be profitable for airlines at roughly one-quarter of Concorde fares. Range: 42,50 nautical miles - Scholl gives Overture's range as sufficient for routes like Tokyo-Seattle and long-haul trips with one stop. Tokyo to Seattle flight time: 4.5 hours - Example of a long nonstop route enabled by Overture. Aviation emissions share: 2% to 2.5% - Scholl cites aviation's contribution to global carbon emissions when discussing sustainability. Prototype size comparison: XB-1 is about one-third the size of Overture - Explains why Boom used the smaller demonstrator aircraft to learn before building the full airliner. Denver facility size: roughly 50,000 square feet - Where Boom assembled the XP-1 prototype. Production timeline: end of 2024 - Scholl says Boom expects to be in production by the end of 2024. First airplane delivery: 2026 - Target for the first Overture aircraft. Flight testing start for Overture: 2027 - Planned beginning of the full-aircraft flight test campaign. Passenger certification target: end of 2029 - Boom's goal for certifying Overture to carry passengers.

Pivotal Quotes: "Speed inherently has to cost more." — Guy Raz quoting conventional wisdom: Used as one of the assumptions Scholl challenged when evaluating whether supersonic flight could be commercially viable. "We want flying fast to be less expensive than flying slow." — Blake Scholl: Summarizes Boom's core mission and pricing ambition for Overture. "This comes down to courage." — Blake Scholl: Scholl reflects on deciding to pursue the seemingly impossible goal of mainstream supersonic flight.

Implications: If Boom succeeds, long-haul travel could become dramatically faster without new noise burdens and with lower climate impact through sustainable fuel, potentially reshaping business travel, global connectivity, and the economics of premium aviation.
