Previously unreported analysis by the Federal Aviation Administration of the first Boeing Max crash suggests it "didn't take that much" for a sensor to malfunction and that a similar disaster was possible.

Just over five months after that Lion Air crash in Indonesia, Ethiopian Airlines Flight 302 crashed in March, leading to the worldwide grounding of all 737 Max aircraft. The two crashes killed 346 people.

According to The Wall Street Journal, the first crash prompted the FAA to inform pilots about the risk of a sensor malfunction that could repeatedly push the nose of a plane down.
