Every day since March 8，people all over the world keep asking the same question：Where did Malaysia Airlines Flight MH370go？It turns out to be the biggest mystery in modern aviation （航空） history．
In the early hours of March 8，a Boeing 777took off from Malaysia's capital Kuala Lumpur （吉隆坡）．It was heading to Beijing．
But about two hours into the flight，the plane lost contact．There were 239people on board the Malaysia Airlines flight，including 154Chinese．
About 12countries，including China，the US and Australia，have joined the search for the missing plane and passengers．The plane's disappearance was a"mystery"，said officials．The plane was flying at a height of more than 10，000meters when it suddenly lost contact．The weather was clear．The pilots didn't make any distress calls （求救信號）．When a plane crashes，broken parts are usually recovered．But up to April 2，officials have not found anything．People are also talking about a possible hijacking．Interpol （國際刑警組織） said that two people on the flight used stolen passports．But that information alone isn't evidence（證據(jù)） of a hijack．
The investigation （調(diào)查） is still going on．It could take months or even years to find out what happened to the flight．
"We are looking at all possibilities，"said Malaysian Transport Minister Hishamuddin Hussein．"The most important thing now is to find the plane．"
On March 24came a piece of sad news．Malaysian Prime Minister Najib Razak said that the plane"ended in the southern Indian Ocean"．Everyone on the plane died．But the mystery is still not solved．Nobody is giving up．China has said it will work hard to find out the truth at all costs．
