Blake Scholl: Why Plane Speed Stalled, Supersonic Commercial Flight, & Revolutionizing the Engine

Summary

Blake Scholl makes the case that Boom Supersonic is reviving passenger supersonic flight after decades of stagnation, combining a small-team aerospace build, sonic-boom mitigation, and a push to permanently legalize overland supersonic travel. He says XB-1 became the first privately developed jet to break the sound barrier and explains Boom’s “boomless cruise” concept as atmospheric refraction that steers the boom upward. Scholl then details Boom’s break with Rolls-Royce and move to vertically integrate engine development, including in-house parts manufacturing down to turbine blades. The most surprising turn is a dual-use strategy for the same engine core: generator-based power modules for data centers that can be deployed behind the meter without water. He closes with specific performance and business claims for Overture, including Mach 1.7 transatlantic service, about 3.5-hour Atlantic crossings, and a break-even fare around $3,500.

Notes

• Boom is pitching a return of commercial supersonic passenger travel, with a small-team, vertically built aircraft program.
• Scholl frames the company as a challenger to Boeing's pace of innovation.
• Boom's early prototype path included a cardboard-and-plywood mockup, before evolving into a real supersonic aircraft program.
• XB-1 is described as the first privately developed jet to break the sound barrier.
• Boom claims XB-1 reached roughly Mach 1.1 in its sound-barrier flight.
• The company says boomless cruise uses atmospheric refraction to send the sonic boom upward rather than to the ground.
• Scholl says the U.S. overland supersonic ban began in 1973 and was ended by executive order on June 6 of the prior year.
• Boom says the Supersonic Legalization Act passed the House unanimously and cleared Senate Commerce unanimously.
• Scholl says Boom abandoned outsourcing engine development to Rolls-Royce after that path failed.
• The engine program is now fully in-house, including design and manufacturing of parts down to turbine blades.
• Boom says its first vertically integrated engine core is already being assembled and will enter a test stand next month.
• The core is intended to operate in the high-power, hot environment demanded by Mach 1.7-class propulsion.
• Boom is repurposing the engine core into a generator by removing the fan and attaching a generator on the back.
• The first non-aviation application is behind-the-meter power for data centers.
• Boom says the ground-power system can be packaged into a couple of trailers and deliver 42 MW.
• The data-center power concept is described as water-free because the engine is designed to run hot.
• Boom says its factory made its first parts last week.
• The manufacturing plan is to scale to multiple gigawatts per year.
• Boom's five-year target is to add 10+ GW to the grid.
• Scholl argues the engine will be the most tested new jet engine ever because it is first validated on the ground.
• Over water, Scholl says Boom can fly twice as fast as today with no sonic boom concern.
• Over land, Boom says boomless cruise enables roughly 50% faster flight than current commercial speeds.
• Scholl gives a target Atlantic crossing of about 3.5 hours at Mach 1.7.
• The quoted break-even fare for that route is about $3,500 round trip.
• Scholl says boomless cruise has a Mach cutoff around 1.3.
• That Mach 1.3 limit is described as about 50% faster than current flight.
• Boom says demand for the ground-power product is already extreme.
• Scholl says the first engine will run next month before being auctioned off.
• Boom is 12 years old and still pushing toward multiple aircraft categories.
• Scholl's end-state metric is when children treat six-hour cross-country travel as antiquated.
• Boom says it has 130 orders from major airlines.
• The order book is being used to support the case that there is real airline demand for supersonic service.
• Scholl says Boom built the airplane with roughly 50 people, underscoring the lean execution model.
• The company claims full-speed supersonic flight is possible over water because there is no one below to hear the boom.
• Scholl describes Overture as targeting Mach 1.7, tying the airliner to the new engine program.
• The company presents its engine work as an example of digital design paired with digital manufacturing.
• Boom claims the engine is designed for sustained high-power operation rather than a brief burst profile.
• Boom's data-center strategy effectively turns aviation R&D into a power-generation product line.
• The company portrays the ground-power business as a monetization path with exceptionally high demand.
• The long-term ambition is to normalize high-speed travel across all passenger classes, not just premium niches.
