According to the FAA's Emergency Order, the new data "from satellite-based tracking of the aircraft's flight path" from Sunday's wreckage "indicates some similarities" between the Ethiopian and Indonesian incidents. The FAA stressed in the statement that these findings "warrant further investigation of the possibility of a shared cause for the two incidents that needs to be better understood and addressed".
Earlier in the day, US President Donald Trump said that Washington would issue an emergency order to ground all Boeing 737 Max 8 and 737 Max 9 series planes following the Ethiopian crash.
