A disgruntled passenger filmed a "nightmare" eight-hour flight where a "demonic" child screamed almost the entire time.
The child can be seen climbing on top of the seats and screeching before the flight has even taken off yet.
But while many might have hoped the young boy may have settled down and watched a film – he doesn’t.
Instead he runs around the aircraft for almost the entire eight-hours while travelling from Germany to Newark, New Jersey.
It is not clear from the video which airline the boy and his family were flying with.
The video was uploaded onto YouTube last summer by Shane Townley who captioned it "demonic child screams and runs through an 8 hour flight".
He wrote: "Watch as this kid runs and screams throughout the entire flight while the mother does little to nothing to stop him.
"3 years old on a 8 hour flight from Germany to Newark NJ. He never quits!"
In the video the child can be seen climbing on top of the seats while his mother asks him to sit.
The boy then starts his "demonic screams" as the video suggests, which takes over the plane.
Filming the noise from several rows back the screaming can clearly be heard.
Before the flight has even taken off yet the child’s mother desperately asks the flight attendant to "get the WiFi going so we can get the iPad going".
She can be heard trying to calm her child down but he continues his screams, ignoring his mother’s pleas.
As the hours pass passengers can even be seen covering their ears as the unruly child runs up and down the aisles while screaming at the top of his lungs.
And it is a scene that continues throughout the majority of the flight.
After leaving the plane to go into the airport another passenger can be heard saying: "What a nightmare, oh my God – eight hours of screaming" as they wheel their suitcase down the ramp.
Commenting on the clip one person said: "Sadly this is happening more and more on flights, unruly kids and babies and exhausted parents.
"Even noise cancellation headphones would not have drowned out this terror.
"Total lack of discipline..perhaps crew should have removed said child and parents for violating safety regulations."
Another person wrote: "If this started before the plane took off, the plane should have taxied back to the terminal and kicked the kid and his parents off. This kind of behaviour is just unacceptable."
And another suggested: "Call an exorcist."
