Pretty clearly not a terrorist, although given the circumstances and the unfortunate way in which her craziness manifested itself, you can understand how she might have made people onboard a little jumpy:

In the affidavit, Choldin says flight attendants noticed Mayo about 90 minutes into the flight because she was pushing against the aircraft bulkhead. When the attendant told her to return to her seat, Mayo said she wanted to speak to an air marshal and made statements about knowing that people wanted to see what was in her bag…

Later during the flight, according to the affidavit, Mayo asked a flight attendant: “Is this a training flight for United Flight 93?” The flight attendant didn’t know if she made a mistake because the flight was actually Flight 923, or if she was referring to Flight 93, the hijacked plane that crashed in Pennsylvania on Sept. 11…

She also wrote in a note and said to flight attendants that she had been in a country illegally, and later said she had photographs of Pakistan…

Flight attendants summoned the captain, who spoke to Mayo. During the conversation, she made reference to there being “six steps to building some unspecified thing.”

“She made reference to being with people associated with two words. She stated that she could not say what the two words were because the last time that she had said the two words she had been kicked off of a flight in the United Arab Emirates,” according to the affidavit.

The captain and purser both believed that she was referring to al-Qaeda, Choldin wrote.

She ended up pulling down her pants and squatting on the floor of the cabin to pee, which probably should have clued them in, at the very least, to the fact that they weren’t dealing with a Zarqawi-level operative. Not that you’d want to take any chances.

Here’s something she wrote for the Pakistani paper Dawn. No comment.
