A mass brawl erupted between British passengers on a flight from Turkey to Manchester, forcing the jet to make an emergency diversion.
Chaotic footage has since emerged of Thursday's Jet2 fight, capturing passengers screaming as others exchanged blows and wrestled in the aisle mid-air.
Now, a 21-year-old passenger from Sheffield who was on board the flight has described the scenes to the Daily Mail, and explained what triggered the 'shocking and frightening' brawl.
The unnamed source claimed that the trouble began when a bald man who had recently undergone a hair transplant loudly began asking other passengers if they wanted to listen to music.
'Some people said yes because he was already being so loud,' he said. 'I think him and another bloke had definitely been drinking before or on the flight because their beaviour just wasn't normal'.
But cabin crew quickly intervened and requested he turn it down.
The man, who can be seen in footage wearing a grey Trailberg jacket, then began shouting at the air hostess, according to the anonymous passenger.
'She went and got her supervisor but he was being so rude, just swearing and shouting at her, I've not seen anything like it,' he said.
Around 10 minutes later, another altercation erupted when he allegedly asked two teenage brothers sitting in front of him, aged 16 and 18, if they would buy him cigarettes as he had reached his £210 spending limit on board.
The older brother refused, causing the man to start swearing at them, according to the Sheffield resident who filmed the scenes.
'He told him to f* off, he was swearing and yelling at them it was awful, I wouldn't wish anything like that on anyone,' he said. 'It was so scary, there were kids on the plane'.
The 18-year-old, who is not seen in footage, then left his seat to go to the bathroom before his mother walked over to confront the man who had asked for the cigarettes.
According to the passenger, the woman remained calm as she told the man to leave her son alone and that he would not be giving him any money.
'She didn't say anything bad at all, she was very respectful and was just asking the man to stay away from her son'.
But this simple interaction prompted the man to start hurling verbal abuse towards the mother, as he told her to 'f off b*', the passenger said.
The younger son then allegedly approached the man to tell him to 'stop swearing at my mum' but this only angered the man more as he began yelling loudly at the pair, startling nearby passengers.
The individual filming the drama soon became involved in the incident as he attempted to stand up for the woman who was being yelled at.
But things quickly took a turn for the worse when the male passenger allegedly began making racist remarks.
'He kept on asking me if I wanted to fight, but then he called me a Muslim mug. He said: "Bet you don't want to fight me you Muslim mug". It was shocking, an unreal experience,' he said.
'This is when everyone began shouting and fighting, some more people were filming now and people were just asking him: "Why are you being racist?".
In his footage, the man, who was standing in the plane aisle could be seen attempting to snatch a woman's phone who was filming the scenes unfold.
He is then seen grabbing a pair of glasses off a man's face before throwing them to the side, prompting the man to retaliate by shoving him.
This man was allegedly the cousin of the two teenagers who were asked by the disruptive passenger to buy cigarettes for.
Passengers previously claimed one of those detained had been drinking heavily and making racist remarks before the situation escalated.
Police boarded the aircraft on landing and took two individuals into custody.
The brawl erupted between British passengers and prompted the flight to make an emergency landing in Brussels.
A third man then joined in shoving the would-be phone snatcher, prompting all hell to break loose.
During the ensuing altercation a woman could be heard screaming as a female flight attendant rushed in to try and separate those fighting.
One man placed another in a headlock, and terrified families and elderly travellers reportedly became caught up in the disorder.
'Everyone was shouting and fighting. People were even crying and there were children on the plane. I never imagined something like that could happen,' the source said.
In his footage, a pair of men standing in the background also appeared to be embroiled in a verbal altercation as shouts and yells erupt across the plane.
Multiple passengers then attempted to intervene to calm the situation, with cabin crew seen also trying to ease things.
Witnesses described seeing blood on seats and teeth scattered on the floor.
'I didn't see any teeth, but I heard that other passengers were saying that he had just gotten his teeth in Turkey and some had been knocked out in the fight.
'He was covered in blood though at the end. His whole head was bloody,' he recalled.
Several passengers were later spotted giving basic first aid to those involved.
'People were coming back from their holidays and this is the last thing you would want coming home. It really was shocking.
'We were meant to land back in Manchester at around 8pm but we didn't end up getting back until around 10.30pm after we had to emergency land in Brussels.'
According to the flyer, when they landed in Brussels, the police still took around 20 minutes to board the plane and detain the man, and another male passenger who had been fighting.
The pilot later told passengers that in 30 years of flying he could count his emergency landings on one hand, adding he had never witnessed an incident as violent.
The aircraft later continued to Manchester following the unscheduled diversion.
