Catherine Mayo is the name of the woman detained in the incident aboard a United Airlines flight from London forced to land in Boston, after she allegedly disrupted it. Eagle—eyed Sweetness & Light noticed that some accounts referred to the 59 year old as a journalist, and that she is reported to have uttered the word "Pakistan" while allegedly disrupting the flight.

Putting two and two together, S&L found an article which suggests the alleged disrupter might be the same Catherine Mayo who has written some lefty rants published in Pakistan.

This has yet to be confirmed, of course.

A second loopy article by Cathy Mayo, who says she is from Vermont.
