Malaysia Airlines (MAS) has reportedly introduced new cockpit security measures. The rules require crew to guard the cockpit while food is being delivered to the pilots, and while either pilot is using the toilet. Malaysia’s The Star newspaper said that the carrier increased its security a week after flight MH370 went missing. Missman Leham, MAS’ chief pilot for flight safety and human factors, reportedly sent a message to all flight deck crews. Malaysia Airports Holdings Board has reportedly also stepped up security on the ground.
