Everybody was Kung Fu fighting...on a plane. A Chinese airline has started Kung Fu training for their staff so they can deal with on-board attacks.

Hong Kong Airlines plans to teach their flight attendants wing chun, a form of Kung Fu. It's being taught to deal with frequent attacks on planes. The airline averages that three attacks occur a week. Attacks at airpots have occurred all over the country as the airline industry to dealing with delays, The Telegraph reports.

Angry passengers take their rage over a delayed flight out on the flight attendants and airport staff. It occurs so often that the staff have developed a name for the angry passengers. They call them "king nu zu," or the "air rage tribe."

According to aviation research company FlightStats, only 18 percent of the 22,000 flight at Beijing's Capital airport are on time, making it the worst in the world. It is so bad that no Chinese airport has managed to get more than 50 percent of flights to fly on time. At least eight protests have broken out at departure gates in the past two months.

On July 18, more than 30 passengers attacked security and ran onto the runway because the airport was dealing with seven hours of delays due to bad weather. Two airport staff members were injured when a passenger tried to rip off a flight attendant's name tag in another incident.

"The passengers were very emotional and unstable," Ni Xuying said of that incident.

In another incident, a teacher name Liu Weiwei got angry when her flight from Wenzhou to Beijing was cancelled. She slapped and kicked an Air China flight attendant, saying that she was mad that no one offered her any refreshments.

The air traffic is controlled by the People's Liberation Army, which is one of the reasons for delays and they become worse when bad weather forces flight to be cancelled or delayed.
