One day before the deadly crash of a Lion Air plane on Oct. 29 last year, pilots flying that Boeing 737 Max 8 lost control of the aircraft — but they were saved by an off-duty colleague riding in the cockpit, Bloomberg reported on Wednesday.

That off-duty pilot correctly identified the problem the crew was facing and guided them to disable the flight control system in order to save the plane, according to the report, which cited two people familiar with the investigation in Indonesia.
