Boeing delays unveiling of new 777X after 737 Ethiopian crash


157 people were killed when a Boeing 737 MAX 8 operated by Ethiopian Airlines crashed just minutes after take-off from Addis Ababa en route to Nairobi on Sunday.

Airlines and aviation authorities around the world have grounded their Boeing 737 Max fleets and President Donald Trump has finally spoken out on the plane that's been connected to two deadly crashes.

A source at one Chinese operator of 737 MAX jets told Reuters the airline had stopped operations after getting a notice early on Monday.

There were nine Ethiopians and eight each from Italy and the United States. The plane ploughed into the ground at Hejere near Bishoftu, scattering debris like a shredded book, a battered passport and business cards in multiple languages. United was the only US carrier affected, with six planes grounded.

The president did not specifically mention Boeing or the recent crash in a tweet in which he said, among other things, "I don't want Albert Einstein to be my pilot".

Boeing has described the MAX series as its fastest-selling aeroplane ever, with more than 5,000 orders placed to date from about 100 customers.

The Canadian Civil Aircraft Register shows airlines here have 41 of the new Boeing 737 model.

A pilot who saw the crash site minutes after the disaster told the AP that the plane appeared to have "slid directly into the ground".

Boeing said had been working to enhance flight control software that would be deployed across the 737 MAX fleet in the coming weeks.

A Canadian air carrier has chose to ground its small fleet of Boeing 737 MAX 8 aircraft, following the lead of other countries. "The United States Federal Aviation Administration is not mandating any further action at this time, and based on the information now available, we do not have any basis to issue new guidance to operators".

Boeing, the world's biggest planemaker, which has seen billions of dollars wiped off its market value since the crash, said it understood the countries' actions but retained "full confidence" in the 737 MAX and had safety as its priority.

IAG ordered 18 of the 777-9, the largest version of the wide-body jet, the plane maker said at the time.

Many other things could have caused the plane to climb and descend, Cox said.

Aviation experts continue to investigate Sunday's crash, and the cause has not yet been determined.

"Nobody should use this unsafe plane", another said.

She asked her husband to check if they were scheduled to fly on a 737 Max 8. "Our Flight, Flight Service, Tech Ops and Safety teams, along with the Allied Pilots Association (APA) and Association of Professional Flight Attendants (APFA), will closely monitor the investigation in Ethiopia, which is our standard protocol for any aircraft accident", the airline spokesperson added.

Boeing's stock fell 7 per cent to $391.80 in afternoon trading.

Both Addis Ababa and Nairobi are major hubs for humanitarian workers, and some had been on their way to a large United Nations environmental conference set to begin Monday in Nairobi.

Still, Browder, who works for a construction-industry trade group and flies several times a month, said he would be "a bit apprehensive" about getting on a 737 MAX.

"People have a vastly exaggerated understanding of what cockpit automation actually does, and how pilots interact with that automation", Smith said.
