Lion Air pilots were desperately looking for a solution

The pilots of the fateful Boeing 737 MAX 8 from Lion Air consulted another manual in the run-up to the crash.

The plane crashed in the Java Sea last October. All 189 passengers were killed. The way in which the pilots struggle with the device can be heard on the cockpit voice recorder, one of the black boxes. A Boeing 737 MAX 8 also recently crashed in Ethiopia.
