美聯航悍然啟用911失事航班編號

????航空公司通常會停止使用墜毀航班的編號，但今年5月，聯合航空公司（United Airlines）做出了一項錯誤決定，恢復使用聯航93號航班與聯航175號航班編號。這兩架航班在911事件中被劫持，并最終墜毀，它們的編號成為這家航空公司最著名的失事航班編號。

????之后，聯合航空公司很快致歉，并在這兩個航班恢復飛行之前取消了這兩個編號。公司表示，在聯合航空公司與大陸航空公司（Continental Airlines）合并之后，需要對航班編號進行統一，所有編號均是由計算機自動生成。

????聯航93號航班因同名電影而出名。這架航班在賓夕法尼亞州尚克斯維爾鎮墜毀。飛機墜毀之前，機上的乘客重新奪取了飛機控制權。——克里斯?伊西多爾

United Airlines' unfortunate flight numbers

????Airlines typically retire the number of any flight that ends in a crash. But in May, United Airlines mistakenly brought back the numbers of its two most famous crashes -- United 93 and United 175, the airline's flights that were hijacked on Sept. 11.

????United quickly apologized and immediately removed the numbers before any of the flights got close to taking off. It said the numbers had been generated by a computer as it aligned flight numbers between United and Continental Airlines following the merger.

????United 93 achieved a lasting recognition from the movie of the same name about the passengers who regained control of the flight before it crashed into Shanksville, Pa. -- Chris Isidore
