United Airlines CEO Scott Kirby’s remarks put Boom Supersonic’s 2029 Overture goal in doubt and leave the timetable for certification and first passenger service unresolved.
“It’s not going to happen in ’29. It’s going to take longer,” Kirby said in an interview released Oct. 28. The remark did not tie the deadline to either type certification or the first passenger service. Earlier company projections put each event in 2029.
United’s deal covers 15 Overture jets if they satisfy the airline’s requirements. The carrier also has an option on 35 more.
Boom announced the Sprint Core prototype’s completion on Oct. 22. The core is intended for Symphony, the engine planned for Overture, and Superpower, Boom’s 42-megawatt natural-gas turbine for AI data centers.
Boom plans to test the core at Colorado Air and Space Port. The company expects its first ignition before Thanksgiving 2026.
