Lion Air pilots scoured handbook in minutes before crash-sources

The pilots of a doomed Lion Air Boeing 737 MAX scrambled through a handbook to understand why the jet was lurching downwards in the final minutes before it hit the water, people with knowledge of the cockpit voice recorder contents said. The investigation into the crash last October has taken on new relevance as the US FAA and other regulators grounded the model last week after a second deadly accident in Ethiopia. Investigators examining the Indonesian crash are considering how a computer ordered the plane to dive in response to data from a faulty sensor and whether the pilots had enough training to respond appropriately to the emergency, among other factors. Following the second fatal accident, US authorities are reviewing whether enough was done to ensure the plane was safe to fly. <br/>
