Shocking moment passenger is pinned down by flyers and tied up with shoelaces after SMASHING plane window

THIS is the shocking moment a passenger is pinned down and tied up with shoelaces by his fellow flyers after smashing a window mid-flight.

The unidentified man started behaving erratically 20 minutes into the Frontier Airlines flight from Denver to Houston, Texas on Tuesday night.

Terrifying footage shows several passengers forcibly holding him down as he is spread across several seats.

Those grappling him appear to be physically struggling to control the crazed flyer as he violently tries to get free.

One man can be seen holding the suspect's head down as he shakes it from side to side before his hands are tied behind his back with shoelaces.

The man allegedly began punching the seat in front of him before cracking a window with his foot.

Pictures of the aftermath show the window with cracks stretching both the length and width of it.

The area around it is also damaged and shoe scuff marks can be seen.

Victoria Clark, who was sitting in the seat in front, said: “The flight attendants, they just disappeared – they went to go ask for help but I don’t know where they went at the time.

“It’s just me and this man and I start freaking out, having a panic attack.

"Tears, I start screaming for help, 'Somebody come help us, I’m scared'."

Victoria, who was flying with her three-year-old, was forced to move to escape the potential threat.

It was at this point that the man started to kick the window.

It took six men to hold him down, and he remained restrained for the remainder of the hour-and-a-half flight.

Victoria's fiancée was among the group who pinned him down.

Police detained the man when the flight landed at Bush Intercontinental Airport at 11:10p.m.

As he was escorted away, he could be seen restrained in a wheelchair.

The damage to the window did not pose a threat to the safety of the plane, and it was able to finish its journey without issue.

It is not currently known what the motive was behind the man's outburst.

Houston Police have not released the man’s name or given any reason for the outburst.

The Sun has contacted Frontier Airlines and the Houston Police Department for comment.
