https://phys.org/news/2019-03-grounding-boeing-touchy-subject-authorities.html Looks like Boeing has a major problem on their hands with their 737 MAX 8 aeroplanes. They have a full order book and are a major employer in the USA. As well as their planes being a big trading chip in their ongoing trade fight white China. I think this will be one of the fastest investigations ever seen. It has to be. If they loose another one of these planes it could destroy the company, ground hundreds of planes around the world and really hurt the American economy.
