The Boeing plane involved in the Lion Air crash in Indonesia in October, which killed 189 people, "was no longer airworthy and it should not have kept flying", investigators said. The aircraft's anti-stall safety system apparently failed, but a preliminary report also highlighted airline safety as another factor. Pilots on the plane's penultimate flight reported the same anti-stall problem, and it had recurring air-speed indicator and sensor malfunctions, but Lion Air had deemed the plane safe to continue flying. The transport safety committee advised Lion Air, which has a chequered record, to improve its safety procedures and culture.
