Hijacker Mohammed Atta Makes The First of Two Accidental Transmissions From Flight 11 to Ground Control

[Archangel]

Hijacker Mohammed Atta makes the first of two accidental transmissions from Flight 11 to ground control (apparently in an attempt to communicate with the plane's cabin). Attempting to communicate with passengers and crew inside Flight 11's cabin, hijacker Mohamed Atta presses the wrong button, broadcasting instead to air traffic control and unwittingly alerting controllers to the attacks. Minutes later, Atta again makes an unintended transmission to ground control. At least one of Atta's transmissions is picked up by the pilot of Flight 175, Victor J. Saracini, who will inform the Federal Aviation Administration of what he has heard minutes before his own plane is hijacked.
