Have you ever snuck through TSA security, without being a passenger? Chances are unlikely, however for one passenger she’s managed to sneak through airport security at least 10 different times!!

Per the NY Post,

The 66-year-old “serial stowaway†was caught yet again after sneaking through security at Chicago’s O’Hare Airport last week without a ticket or passport — but not before she made it all the way to London.

Hartman, who lives in Grayslake, Ill., has made a hobby of ducking the TSA. Her arrest last week was at least the 10th time she’s been caught trying to slip past airport security without a plane ticket.

Sources told CBS Chicago that the most recent security footage shows Hartman wandering around O’Hare for two days last week before boarding a British Airways flight Monday. She managed to evade the gate attendant by “blending in with the passengers,†Chicago police told the Chicago Sun-Times. Sources did not address how she made it past TSA checkpoints to get to the gate.

Once on the aircraft, she hid in the bathroom, then found an empty seat. The airline warned Heathrow airport officials that they had a stowaway on the incoming flight. The pesky passenger was sent back to the US when she couldn’t produce a passport and was arrested Thursday upon arrival at O’Hare.

While she was able to sneak through without getting her boarding pass nor ID checked, the TSA claims that she was in fact screened and did clear security, though it’s unclear on how the TSA keeps missing her.
