Ask the Editors: It is near axiom that new models need to offer 15% better economics, and that improvement only comes from major changes.
Aircraft & Propulsion

By Guy Norris
Ask the Editors: The 737’s baseline configuration has been remarkably resilient for decades, but it is unlikely to evolve beyond the -10.
Air Transport

By Thierry Dubois
Ask the editors: Is it worthwhile to change aviation’s fuel infrastructure? The answer might be the use of LNG as a transition to SAF.
