紐約飛機水上迫降新聞分析之一

據美聯社報道：
The pilot twice told air controllers that he was unable to make the proper turn after reporting a "double bird strike."
The tower believed Sullenberger meant that both his jet engines had been damaged by bird impacts.

從這段文字中可以看出：機長並沒有報告過發動機損毀。

如果這是相關內容的全部，就產生了兩個問題：
1. 機長為什麽不報告發動機的運行情況？
2. 塔台為什麽不跟蹤詢問發動機的運行情況，而憑猜測作決定？
