Maybe it's just me, but you'd figure that with today's high levels of transportation security that stowing away on a commercial airliner would be something that just can't and/or doesn't happen. And, you'd be wrong.

It does happen, and Marilyn Hartman, a 66-year old Grayslake woman, has made somewhat of a habit doing just that. She's made a habit out of being arrested, too. Sunday, at O'Hare International Airport--it happened again.

From Fox News:

A woman known as the “serial stowaway” was arrested again on Sunday at Chicago O’Hare International Airport, just three days after she was released from jail after being nabbed for flying ticketless from the Illinois city to London. Police received a disturbance call about a woman refusing to leave the airport, police said in a statement sent to Fox News. She was nowhere to be found when officers arrived. Hartman was later found in O’Hare’s Terminal 3 and was taken into custody. She was charged with a misdemeanor criminal trespass.

After her last arrest for a stowaway trip to London, she was asked 3 times by a judge to stay away from airports. But, Sunday she was back at it again.

Hartman has pulled a similar stunt at least eight times in 2014. In one incident, she slipped past TSA agents and boarded a flight at Mineta San Jose International Airport to Los Angeles, according to WLS. She was eventually caught after landing in Los Angeles.

She was also arrested two times in 2015 within two months at O’Hare and Chicago’s Midway Airport.

Several other times Hartman was taken into custody for wandering airport terminals without a boarding pass, raising suspicions on whether she was preparing for another attempt to board a flight ticketless.

In 2016, Hartman was sentenced in Chicago to six months of house arrest and placed on two years of mental health probation.
