Well, it was the wee small hours, when people normally sleep soundest. I'd hazard a guess some booze helped. There definitely is some negligence on the cabin crews behalf, to obviously not do a thorough check of the plane, before leaving.
However .. she HAS also employed the biggest Rottweiler, in-your-face, attorney... who specialises in cases where he can get maximum media exposure. I'd say there'll be a quiet out-of-court settlement, which will also involve a new Beemer for Fiegler, the attorney...
"The plane landed around 12:30 a.m. but McGuire said she woke up around 4 a.m. with no flight crew attempting to wake her. She wasn’t aware that the cleaning crew had discovered her sleeping and called authorities. After pacing the airplane for 15 minutes, she was met by a TSA agent and two police officers who questioned her for 10 minutes (and who requested to sight MGuire's ID). She’s now suing Trans State Airlines, operators of the United Express flight, for “$25,000 and $75,000, on claims of negligence, infliction of emotional distress, false imprisonment and breach of contract.”
