Boeing has completed the first flight of an autonomous passenger air vehicle (PAV) prototype developed by subsidiary Aurora Flight Sciences.

Startup works to balance high- and low-speed requirements for Mach 2.2 airliner, aiming to approach subsonic noise standards.

Initial European studies of distributed hybrid-electric propulsion underscores the challenges to making the technology feasible for large passenger aircraft.

A few details and the probable choice of engines suggest the aircraft will be conceptually like the retired U.S. F-111, but perhaps a lot bigger.

Industry is already stockpiling components—at no small cost—to prevent production disruption in the event of a “no-deal” Brexit.

In a shocking move just three months after founder Paul Allen's death, Stratolaunch has abandoned development of a family of dedicated launchers and PGA rocket engines.

Air Force Undersecretary Matt Donovan told reporters Jan. 18 that the experimentation campaign will continue and details will be revealed in the fiscal 2020 budget request.

Boom’s Overture supersonic airliner will be as quiet on takeoff and landing as subsonic aircraft flying similar routes today, the startup says, providing more insight into its efforts to reconcile the high-speed and low-speed requirements for its Mach 2.2 commercial aircraft.
