Aboard a packed passenger jet in mid-flight somewhere over Asia, a security guard disables a hijacker by slipping a scarf over his head and pulling him to the ground.

However, the passengers are trainee bodyguards, the hijacker is an instructor, and the plane is a mock-up used for training flight attendants.

Inspired by the missing Malaysia Airlines Flight MH370, China's Tianjiao bodyguard school has introduced a special course on flight safety. Trainees are taught emergency evacuation procedures and close-quarter combat skills so that they can handle situations such as natural disasters and plane hijackings.

The Tianjiao bodyguard school was set up by former soldier Chen Yongqing. He employs former Israeli and Russian military men to put recruits through rigorous training and punishing endurance tests.

Chen says that when he started the bodyguard school, most of his clients were celebrities. Now, he says: "Most of our clients are rich entrepreneurs. It's all related to their business because bodyguards are a status symbol."
