BOSTON -- A Vermont woman who was on a flight that was diverted to Logan International Airport appeared before a judge Thursday.

NewsCenter 5's Jack Harper reported that Catherine Mayo, 59, of Braintree, Vt., was charged with interfering with a flight crew after allegedly disrupting United 923 as it flew from London to Washington, D.C., on Wednesday. She was ordered held pending a detention and probable cause hearing next Thursday.

"Her lawyer has raised some issues concerning mental health, and we believe it is important for her to have an opportunity to have a doctor examine her competency," U.S. Attorney Michael Sullivan said.

FBI officials said that the woman roamed, mumbled, urinated on the floor and exchanged words with the flight crew.

According to an FBI affidavit, at one point she said she had film. "She stated the photographs would be awful, and she indicated they would be related to the people she had been with in the mountains of Pakistan," the affidavit read.

"She also stated she had been in Pakistan, and made reference to being with people associated with two words. The captain and the purser both believed she was referring to al-Qaida," the affidavit continued.

In another exchange, Mayo "referred to there being six steps to building an unspecified thing. The captain and purser thought she was referring to a bomb."

Mayo's ex-husband said that she has emotional issues. Mayo's son said that his mother may have been under stress.

"She might have had a stressful time in Pakistan, just getting out of Pakistan, combined with a long flight, she might have just had a rough time," Mayo's son, Josh Mayo, said.
