Part 7/10:
A significant aspect of the analysis suggests the possibility of military exercises occurring concurrently with the events of September 11. Recorded transmissions indicated concerns about various hijacked flights, including Flight 11, raising questions about whether some of the aircraft were misidentified. A particularly interesting theory suggests an "airplane swap," where a plane from another airline—with a similar tail number—could have been involved in a planned exercise, thus diverting attention from the actual events.
