Documented cause
Boom Supersonic promised to revive commercial supersonic passenger travel with its Overture aircraft, targeting 2029 for first commercial flights. The company secured orders and pre-orders from United, American, and Japan Airlines, raising $700M and generating enormous press. But in late 2023, Rolls-Royce withdrew from the engine development partnership after years of collaboration — a stunning development that left Boom without a certified engine supplier for its core product. The company announced it would develop its own engine, a task that typically takes a decade and billions of dollars. By 2024 the company was restructuring with significant layoffs.
Lesson
“Aerospace hardware has decade-scale development cycles and supplier ecosystem dependencies — VC timelines and aerospace timelines are fundamentally incompatible.”

FAQ
Does Boom Supersonic have actual airline orders?
Boom had letters of intent from United, American, and Japan Airlines — conditional commitments, not firm orders with deposits. Letters of intent are marketing tools until backed by non-refundable deposits.
What happened with Boom's engine?
Rolls-Royce withdrew from the engine development partnership in late 2023. Boom announced plans to develop its own engine — a multi-billion dollar, decade-long project that further delayed the Overture timeline.
