A passenger has been accused of undressing on a flight, demanding to smoke and trying to break into the cockpit while telling alarmed passengers they would all die.
Anzhelika Moskvitina, 49, bit a male flight attendant who sought to restrain her on an Aeroflot flight in Russia, it has been claimed.
The 33,000ft high drama began when she locked herself in the toilet and smoked, it is claimed.
She bared her chest in front of other passengers - including children - on the flight from Stavropol to Moscow.
Business class passengers had to assist the crew to restrain her as they forced her bra back on, then put her in plastic handcuffs on the captain’s orders.
She had got up to smoke in the toilet as the plane was going through turbulence.
Witnesses said she had bared her chest and shouted to fellow passengers that they were all doomed.
She also sought to force her way into the cockpit.
A video caught the moment when the woman - suspected of being intoxicated - was arguing with flight crew as they sought to pacify her.
“Lady, take a seat and get dressed,” she was ordered by the crew.
“Where are your clothes?”
She was asked: “Do you understand you're violating the behaviour rules on the plane? There are children here. Respect them at least.”
She replied: “I respect children. What’s more, I love children. I understand I'll go to the mental hospital or a prison. But I want to go to the cockpit.”
She was told her demand was “senseless”.
As the crew sought to make her dress, she replied: “Please go away from me. Kill me here, but I will smoke.”
She was urged to “calm down”, but repeated to the crew to “leave me alone” and “let me go”.
Eventually she was cuffed and a doctor on board monitored her as the plane landed at Moscow’s Sheremetyevo airport when she was held by police.
The flight attendant needed medical treatment.
Aeroflot immediately demanded new laws covering air rage including a black list of unruly passengers.
The woman, from Moscow, had been in “an inadequate state” and “grossly violated the rules of conduct on board the aircraft”, said the airline.
She “ignored repeated warnings from the crew and tried to break into the cockpit", the airline added.
It continued: “Due to the passenger's destructive behaviour, the aircraft commander decided to use a means of restraint on her.
“Aeroflot emphasises that this case again proves the urgent need at the legislative level to toughen punishment for air rowdies, including creating a single blacklist of destructive passengers for all airlines.”
The woman has been warned that she is liable to face criminal charges.
