Part 3/7:
The researcher reviewed several official final reports from the National Transportation Safety Board (NTSB) regarding the crashes. A notable finding was that, across all four flights involved—American Airlines Flight 11, United Airlines Flight 175, American Airlines Flight 77, and United Airlines Flight 93—no ELTs were activated at the time of impact.
Curiously, ELTs for flights 11 and 175 were activated two and four minutes earlier than the actual crashes, respectively. The apparent malfunction raises questions about the reliability of the devices in these situations. Furthermore, the absence of recorded data concerning the aircraft, including serial numbers, in the official reports is striking.
