Ethiopia has released preliminary findings from its investigation into last month’s fatal crash of Ethiopian Airlines Flight 302, which killed all 157 crew and passengers on board. Ethiopia’s transport minister said the pilots of the Boeing 737 MAX 8 jet followed normal procedures but were unable to overcome a flaw in the plane’s software that automatically pushed the plane’s nose down. The report found similarities in the technical failures experienced by pilots of October’s Indonesian Lion Air Flight 610, which also crashed just minutes after takeoff, killing all 189 people on board. The Federal Aviation Administration has grounded all 737 MAX aircraft while Boeing works on fixes to the planes’ software.
