The US has followed the lead of other nations including Australia and has grounded Boeing’s 737 MAX aircraft after an Ethiopian Airlines flight crashed and killed all passengers aboard on Sunday.

The US Federal Aviation Administration announced it has ordered the temporary grounding of the aircraft either operated by US airlines or flying in US territory, which they decided from data and new evidence obtained from the Ethiopian Airlines crash site.

The federal agency said the emergency order of prohibition on the Boeing 737 MAX 8 and 737 MAX 9 will remain in place while the investigation into this week’s crash continues.

However the German Federal Bureau of Aircraft Accident Investigation responsible for investigating the Ethiopian Airlines crash said they are unable to investigate the plane’s recovered black box because the new aircraft operates new software.
