Minutes after take-off, the pilots of an Ethiopian Airlines 737 MAX were caught in a bad situation.
A key sensor had been wrecked, possibly by a bird strike. As soon as they retracted the landing gear, flaps and slats, it began to feed faulty data into the Maneuvering Characteristics Augmentation System (MCAS), designed to prevent stalls.
Flying faster than recommended, the crew struggled with MCAS. But the high speed made it nearly impossible to use the controls to pull the nose up.
Moments later, the Boeing Co jet hit the ground, killing all 157 people onboard after six minutes of flight.
Ethiopian authorities said on Thursday that the pilots followed all the correct procedures in trying to keep MCAS from sending the plane into a fatal dive.
