The crash that killed 157 people, involving Boeing’s newest jet, happened shortly after takeoff from the Ethiopian capital of Addis Ababa on Sunday. It was the second deadly accident involving the aircraft in less than five months.

The other crash involving Boeing's 737 MAX 8 took place on October 29, when a jet owned by Indonesian Lion Air crashed in the Java Sea, taking the lives of 189 passengers and crew.

Monday's trading on Wall Street marked the worst selloff of Boeing stock since September 17 2001, in the days following the 9/11 attacks.

The shares bounced back to trade at $390.18 at 14:20 GMT, still marking a significant drop of nearly 8 percent.

The latest stock plunge wiped out over $28 billion from Boeing’s market value, sending the Dow Jones Industrial Average down 140 points during early trading in New York.

Both accidents involving one of the world’s best-selling passenger jets have been placed under investigation in many countries.

Dozens of airlines worldwide have grounded their fleets of Boeing 737 MAX 8s. Chinese Civil Aviation Administration was the first to put a temporary ban on using the jets by the country’s carriers, with Ethiopia and Indonesia following suit.

Mongolia’s Civil Aviation Authority ordered to the national air carrier MIAT to temporarily suspend its Boeing 737 MAX 8 aircraft operations. Cayman Airways and Royal Air Maroc also grounded the jets.
