Lion air crash is a tragedy that must be investigated

Your story Indonesian plane crashes into sea off Jakarta

(October 29) was sad to read. The aircraft vanished from the radar 13 minutes after take-off and plunged into the water. However, the real cause is not yet known. Lion Air should investigate this incident since the aircraft was only a few months old. After the recent air accidents, people must be thinking twice before taking flights. I pray for the victims.
