Boeing in trouble
Boeing manufactured the infamous 737 MAX model involved in two major crashes that killed hundreds of people in less than a year.
In October of that year, 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 crashed after taking off from Addis Ababa. All 157 people on board died.
The model was grounded and the company was Boeing was fined €2.04 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.
