Passengers with reduced mobility are lobbying for greater accessibility to airline cabins, but certain safety constraints keep the industry from developing a quick solution.
DARPA targets hypersonic defense; USAF wants reusable hypersonics; an unmanned KC-46A tanker? Liebherr/GM team on fuel-cell APU, and UK drone BVLOS milestone.
Feedback on its initial F135 engine upgrade proposal prompted P&W to include increased power and thermal management capability in its Growth Option 2.0 upgrade package.
