A pensioner renowned for making her way onto planes without a boarding pass or passport has managed to do it once again.

Marilyn Jean Hartman sneaked past security at Chicago and boarded a flight to Heathrow Airport in the UK. Authorities arrested her and flew her back to the US, according to Chicago police.

The 66-year-old was detained by British Customers Officials at Heathrow International Airport in London and was charged with criminally trespassing to state land and theft.

Hartman is well known for her efforts at boarding flights without a boarding pass or passport, The Washington Post reports.

She was once caught in 2014 trying to get to Hawaii. In that same year she made it all the way to Los Angeles after trying several times to board a plane in San Jose.

She flew to Florida in 2015 after boarding a plane in Minnesota. She was jailed in Chicago that same year for trying to bypass security at the city’s two major airports.

According to news reports, she usually tries to blend in with big groups to get past airport security.

America'sTransportation Security Administration is investigating how she managed to sneak past security to get to the UK.

“During the initial investigation it was determined that the passenger was screened at the security checkpoint before boarding a flight,” the federal agency said in a statement.

Upon learning of the incident, TSA and its aviation partners, took immediate action to review security practices throughout the airport.

Ms Hartman also has a history of attempted escape from mental health facilities, according to Newshub.
