9. On August 6, 2001, the Presidential Daily Brief included an intelligence memo stating, amongst other things, that “[one threat report said] that bin Ladin wanted to hijack a US aircraft... FBI information since that time indicates patterns of suspicious activity in this country consistent with preparations for hijackings or other types of attacks... CIA and the FBI are investigating a call to our Embassy in the UAE in May saying that a group of Bin Ladin supporters was in the US planning attacks with explosives” (262).

David Ray Griffin

This is something else that looks rather less impressive once you consider the text that Dr Griffin has left out:

We have not been able to corroborate some of the more sensational threat reporting, such as that from a [REDACTED] service in 1998 saying that bin Laden wanted to hijack a U.S. aircraft to gain the release of “Blind Shaykh” Umar 'Abd al-Rahman and other U.S.-held extremists.

This hijacking concern was an old one, from 1998. It was described as “sensational”, and could not be corroborated. And it appears to be a conventional hijacking (you need hostages if you’re hoping to gain the release of someone).

There is the general concern about preparations for hijackings, of course:

Nevertheless, FBI information since that time indicates patterns of suspicious activity in this country consistent with preparations for hijackings or other types of attacks, including recent surveillance of federal buildings in New York.

However there’s nothing here to say that these were suicide hijackings. And in fact a warning about “preparations for hijackings or other types of attacks” is particularly useless, as it could obviously be about anything.

As there’s also nothing here about using planes as weapons, this example fails Dr Griffin’s test, and ours. Read more on interpretations of the Presidential Brief here.
