Boeing has grounded the fleet of its 737 Max aircraft after last week's fatal Ethiopian Airlines crash. Two 737 Max's have crashed in five months. In October, a plane from Indonesia crashed. Aviation experts say the circumstances are similar. Investigators have the black boxes from Ethiopia and will study their data to find reasons for the crash. The USA's aviation administration said it was clear the Ethiopian Airlines and Lion Air flights behaved very similarly.

Boeing hopes the 737 Max is a key part of its future. It has received 5,000 orders for the aircraft and has delivered 371. The grounding has seen its market value drop by nearly $26 billion. Boeing's president said: "We are doing everything…to understand the cause of the accidents, deploy safety enhancements, and help ensure this does not happen again." Boeing said that it "continues to have full confidence in the safety of the 737 Max".
