Chloe Haines pleads guilty after sparking hijack alert by trying to open plane door

An unhinged woman who stormed a cockpit during a flight from the UK to Turkey screaming, “I’m going to f—— kill everyone,” forcing two fighter jets to intercept the flight, pleaded guilty Monday to assault and endangering the safety of an aircraft, according to reports.

Chloe Haines, 26, a Costa Coffee worker who was traveling with her wheelchair-bound grandmother, sparked a hijack alert when she tried to open an emergency exit door during the Jet2 flight on June 22.

She also assaulted cabin crew member Charley Coombe before being restrained by staff and terrified passengers on the flight from London Stansted Airport to Dalaman, Turkey.

Two RAF Typhoon fighters were scrambled to intercept the Airbus A321 — causing a loud sonic boom — and guide it back to London, where the woman was arrested after being captured in dramatic photos lying down in the aisle.

During her rampage, Haines screamed: “I’m going to f—— kill everyone! You are all going to f—— die!”

Haines, of High Wycombe, Buckinghamshire, wept Monday as she admitted to the charges in Chelmsford Crown Court, but denied a charge of drunkenness on an aircraft, according to the Mirror.

Defense lawyer Oliver Saxby said there was “no question that she was drunk” but that the charge of endangering the safety of an aircraft was the “more serious alternative.”

Saxby also said his client was now taking part in an Alcoholics Anonymous program, the Mirror reported.

“She is a troubled young person with a number of serious issues,” he said, adding that 17 days before her midflight meltdown, “she had been sentenced to a community order for not dissimilar offenses.”

“There was a loss of composure and loss of control,” he added.

Judge Charles Gratwicke adjourned sentencing until Jan. 24 but warned Haines that “all sentencing options remain open.” Under her bail conditions, she is unable to travel from a UK airport.

Following the incident, Jet2 said Haines had been hit with a lifetime ban and a $105,000 airline bill.
