Black boxes of Ethiopia's crashed aircraft sent to France

France's air accident investigation agency BEA will analyse black-box flight recorders, a spokesman said.

Investigators released pictures on Thursday of one of the data recorders from the Ethiopian Airlines crash that led to the grounding order.

Canada said on Friday it was suspending its 2019 financial forecasts as a effect of the grounding of Boeing Co's 737 MAX planes, becoming the first major airline to publicly attach dollars and cents to the uncertainty surrounding the new jets. Both black boxes are now in France for analysis with help from three USA investigators.

This follows Sunday's crash of a Nairobi-bound Boeing 737 MAX - 8 operated by Ethiopian Airlines just minutes after takeoff from the country's capital Addis Ababa, killing all 157 on board.

"We would like to apologize to customers who will be affected by temporary cancellations and delays", Norwegian Air said in a statement.

The first Boeing 737 MAX 8 plane landed in Windsor late Wednesday afternoon, with no passengers on board, after the federal government banned the plane from Canadian airspace.

When "Today" host Savannah Guthrie asked Elwell about reports that pilots have not been properly trained in the MCAS system, he said, "Well, the MCAS system is explained in the manuals".

He added that "the evidence we found on the ground made it even more likely the flight path was very close to Lion Air's".

The disaster shook the aviation world, with multiple countries denying entry to the Boeing 737 Max 8 model. Worldwide, approximately 450 machines of the type are registered.

The announcement of the 737 MAX 8 ban in the USA came as several of the planes were still in the air.

According to Business Insider, "One captain complained about the plane's autopilot system, calling the flight manual 'inadequate and nearly criminally insufficient, '" while another pilot declared, "The fact that this airplane requires such jury rigging to fly is a red flag".

The source reported being told that the American investigators left the BEA Thursday night after 12 hours of "doing nothing".

However, the FAA said this week it had ordered Boeing to update its flight software and training.

Ethiopian Airlines CEO said the pilots had complained about "flight control problems". "This includes the 24 MAX 8 aircraft in the American Airlines fleet".

According to The New York Times, air traffic controllers observed the Ethiopian Airlines plane "oscillating up and down by hundreds of feet" prior to the crash.
