Boeing in trouble
Boeing has been plagued with problems ever since manufacturing the infamous 737 MAX modelthat was involved in two deadly crashes in less than a year.
In October 2018, a total of 189 people were killed when a Lion Air Boeing 737 MAX jet slammed into the Java Sea about 12 minutes after take-off from Jakarta on a routine one-hour flight.
In March 2019, an Ethiopian Airlines Flight 302 crashedafter taking off from Addis Ababa. All 157 people on board died.
The model was grounded and the company was Boeing was fined $2.5 billion (€2.04 billion) over claims it defrauded regulators overseeing the 737 MAX model.
The plane that lost contact on Saturday is a much older model. The nearly 27-year-old aircraft did not use the new, questionable autopilot systems built into the current-generation 737 MAX planes.This is a breaking news story and will be updated as more details become available.
