Pilots experienced airspeed, altitude issues before Lion Air crash - investigators

Indonesian investigators said on Thursday the cockpit voice recorder from a crashed Lion Air Boeing Co 737 MAX 8 jet showed pilots were searching for the right checklist in their handbooks and were experiencing airspeed and altitude issues. The details revealed at a press conference corroborated a Reuters report on Wednesday that was based on three sources with knowledge of the cockpit voice recorder's contents. Investigators said they have 90 per cent of the data needed to release a final report, which is expected in August.
