A US pensioner has once again snuck past airport security and this time, she managed to fly to London.
This is the seventh time Marilyn Jean Hartman has been caught flying without a ticket, passport, or boarding pass.
Ms Hartman's methods are unknown, although local media have reported she usually tries to blend in with large groups.
Last Monday (local time), Ms Hartman arrived at Heathrow Airport from Chicago where she was arrested and sent back to the United States.
She was charged with trespassing, theft, felony, and a misdemeanour.
Chicago Department of Aviation spokesperson said no passengers were endangered during the incident.
Police across a number of US states have been aware of the 66-year-old's compulsive behaviour for years.
In 2014, she was caught twice; once trying to fly to Hawaii, and once successfully making it to Los Angeles.
In 2015, she flew from Minnesota to Florida, and was imprisoned in Chicago for attempting to get through security at both of the city's major airports.
The US Transportation Security Administration is investigating how she keeps managing to sneak past customs staff.
Ms Hartman also has a history of attempted escape from mental health facilities.
According to San Francisco magazine, she claimed that everyone from airport staff to President Barack Obama was conspiring to entice her to sneak onto planes in a plan to punish her.
In 2016, she was sentenced to two years of probation and six months at a mental health facility.
