Perhaps it is nothing.
The 9/11 Commission Final Report did not mention it.
The FBI investigated it and interviewed many people, several different times. FBI officials never contested the media reports, nor did it ever release any findings of its investigation publicly.
Perhaps it was not important enough to warrant a note or comment ….. perhaps it is.
During the 10 year anniversary of the attacks, ABC brought us the first-in-a-long-time mainstream news report of the mystery:
Browsing through the 9/11 archive i found some very interesting clips. They describe incidents on 9/11 and 9/13 with regards to alleged foiled hijacking attempts. The latest report speaks of four men and a woman and five men who tried to board airplanes at JFK and LaGuardia on 9/13 with fake ID's, knives and pilot certificates who were arrested. Also there's a report about a possible 5th group of hijackers on United Flight 23 on 9/11 itself.
Why did these stories disappear, and what happened to the suspects. That's what i would like to know.
I did not have time yet to check all the streaming footage at the 9/11 archive (this is just from ABC and NBC), so there might still be more info out there: http://www.archive.org/details/sept_11_tv_archive
