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

Boom Supersonic's in-house jet engine, born from a failed Rolls-Royce partnership, is pivoting into a gigawatt-scale, water-free power business for AI data centers.

• Boom's supersonic milestone: XB-1 became the first privately developed jet to break the sound barrier in 2025, using "boomless cruise" (Mach cutoff) to bend the sonic boom upward so it never reaches the ground.
• Legalization moves fast: The 1973 US supersonic overland ban ended via executive order on June 6, 2025, roughly 115 days after Boom's supersonic flight; the Supersonic Legalization Act has passed the House and Senate Congress unanimously.
