対イラク武力行使

＞ 　　 ところが、９１１当日、戦闘機が出動したのは、なんと８時５２分、つまりアメリカン
　　 航空１１便がノースタワーに激突した後なのです。


戦闘機が出動したのは、８時４６分ですが、これはハイジャックされたということに
気づくのに時間がかかったことが原因です。その辺のいきさつについては下記に
書いてあります。これがふつうでしょう。
ふつう、ハイジャックかどうかはトランスポンダーの認識番号で判定するようです。

ふつうのハイジャックなら、どうせ要求を出すわけですから、すぐに気づかれても
どうということはないのですが、ビルに激突するのが目的なら、犯人側も
なるべく気づかれないように気を配ったのでしょう。
パイロットがトランスポンダーの認識番号をハイジャック用の認識番号に
変更することさえできなかったことが、それを物語っています。


American Airlines Flight 11 FAA Awareness. Although the Boston Center air traffic controller realized at an early stage that there was something wrong with American 11, he did not immediately interpret the plane's failure to respond as a sign that it had been hijacked. At 8:14, when the flight failed to heed his instruction to climb to 35,000 feet, the controller repeatedly tried to raise the flight. He reached out to the pilot on the emergency frequency. Though there was no response, he kept trying to contact the aircraft.106

At 8:21, American 11 turned off its transponder, immediately degrading the information available about the aircraft. The controller told his supervisor that he thought something was seriously wrong with the plane, although neither suspected a hijacking. The supervisor instructed the controller to follow standard procedures for handling a "no radio" aircraft.107

The controller checked to see if American Airlines could establish communication with American 11. He became even more concerned as its route changed, moving into another sector's airspace. Controllers immediately began to move aircraft out of its path, and asked other aircraft in the vicinity to look for American 11.108
