美國航空一架波音777因故障折返北京

An American Airlines Boeing 777 airliner returned to Beijing Capital International Airport this morning after a mechanical malfunction was suspected shortly after it took off from the airport.

美國航空公司的波音777客機今天早上從機場起飛後不久因被懷疑機械故障返回北京首都國際機場。

The Flight AA186 from Beijing to Chicago took off at 10:36am after a 20-minute delay but returned to the airport at 10:54am.

這趟從北京到芝加哥的AA186航班在20分鐘的延遲後於上午10:36起飛，但在上午10:54返回機場。

Witnesses said several ambulances surrounded the aircraft and sprayed foaming water on the undercarriage on the runway after its landing.

目擊者說幾輛救護車包圍了飛機，着陸後在跑道上給飛機起落架噴灑泡沫水。

A source with the airport told Beijing media that the captain noticed a problem with the engines after takeoff and asked to return to the airport.

機場消息人士告訴北京媒體機長起飛後注意到發動機有個問題，要求返回機場。

Since the airliner's fuel tanks were filled at the time of the emergency landing, the captain had to use full brakes to slow it down on the runway and firefighters had to cool down the wheels with water, experts said.

因爲緊急着陸的時候飛機的油箱是滿的，機長必須在跑道上全力剎車使其慢下來，消防隊員不得不用水冷卻輪子，專家說。

The cause of the incident was still under investigation.

事故的原因仍在調查之中。

The B-777 was the model of plane involved in the crash landing of the Asiana Airlines Flight 214 in San Francisco in the United States on Saturday. Two Chinese students were killed while another is still in critical condition.

波音777客機模型與星期六在美國舊金山墜毀的韓亞航空公司214航班有關。兩名中國學生遇難而另一個仍情況危急。
