Boom XB-1 Technology Demonstrator Getting Closer to Supersonic Milestone

Aviation Week reports, “Boom Supersonic’s XB-1 technology demonstrator probed deeper into the transonic speed regime during its ninth test flight from Mojave Air & Space Port, California, on Dec. 13, paving the way for an attempt to reach and exceed Mach 1, now targeted for early 2025. Piloted by Boom chief test pilot Tristan “Geppetto” Brandenburg, the XB-1 expanded the altitude envelope to over 27,700 ft., continued tests of the Flutter Excitation System (FES), and reached a maximum speed of Mach 0.87.”

Boeing’s 777-9 Certification Program Paused to Address Engine Component Cracks

Aviation Week reports, “Cracks in engine attachment components that have stalled Boeing’s 777-9 certification program were found in a fourth test aircraft that has not flown in nearly three years, Aviation Week has learned. The latest discovery, on WH004, is expected to help narrow down Boeing’s investigation into the failures in the thrust links—assemblies that connect the airframe with the aircraft’s GE Aerospace GE9X engines.
