The Malaysian missing airline

On 8th March 2014, A Malaysian Airline with 227 passengers on board, mysteriously vanished on the way from Kuala Lumper to Beijing. Crew members and passengers are from 14 nations. The majority of them are from China. So the Chinese government accuses Malaysia of not being responsible for the missing flight. A multinational search for the flight has found no trace of the plane up to now, and has been still going on the search extending the search area. Even though there are several speculations, no ideal presumption has been found so far.
