Worldwide groundings mount as Boeing faces safety questions with new 737 MAX

Multiple countries and airlines around the world have grounded the Boeing Co. 737 MAX in the wake of the deadly crash of a 737 MAX 8 operated by Ethiopian Airlines on Sunday.  The crash, which killed all 157 people aboard shortly after takeoff from Addis Ababa, Ethiopia, comes five months after the crash of a 737 MAX in Indonesia hat killed 189 people and raises new questions about safety for Boeing’s best-selling aircraft.  Here is a look at some of the latest developments following the Ethiopian Airlines crash:  • Indonesia, China, Grand Cayman Airways, Ethiopian Airlines, Royal Air Morac and Mongolian Airlines have all grounded the Boeing 737 MAX. Aviation analyst Scott Hamilton writes on his Leeham News site that the groundings represent about one-third of the 737 MAX aircraft in service around the world.  • Boeing has postponed a planned rollout event for its new 777X wide-body jet later this week.  • Shares of Boeing (NYSE: BA) dropped as much as 12 percent early Monday, and were down 7.1 percent to $392.45 by the middle of the morning.
