Boeing's new endorsement helps clear the air amidst strong concerns around the 737 Max.

Boeing engineers discovered the discrepancy 'within several months' of the initial Max deliveries in May 2017.

Southwest Airlines Co., the largest Max operator, first learned about the problem with the disagree alert after October's Lion Air 737 Max crash.

There has been no clear indication of what brought down an Ethiopian Airlines Max on Sunday.

The latest crash raises fresh concerns about the safety of the 737 Max.

A mechanic worked on other sensors during a night shift before the departure, but not on the angle-of-attack vane.

The Boeing bulletin suggests pilots on Lion Air 737 Max 8 were battling the plane as its computers commanded a steep dive.

The blast left a plume of thick black smoke and rattled windows in buildings miles away from the launch pad.
