Despite the pandemic decimating air travel, adding to the fallout from a 16-month-old crisis over the 737 MAX grounding after fatal crashes, Smith said the U.S. planemaker was still focused on future investments including new jet development.

Engineers for example were reassessing the product development strategy while building on completed analysis for a now-scrapped mid-market airplane and future production system, Smith said.
