At some point, several male passengers restrained him and got him back in his seat. He was reportedly calm for the rest of the flight and questioned by HPD.

Frontier Airlines reportedly declined to press charges.

What they're saying:

"It was absolutely chaotic. The most terrifying thing I've ever been through. We turned around, and we saw this guy just punching out the window, and immediately we screamed for help," explains passenger Jessica Brown.  

"I was absolutely terrified. My anxiety was really bad. Me and my mom were shaking the whole time, and we were praying the whole time. I didn't know what was going to happen. It was really scary," says 13-year-old Chloe Starcevic.    

Passengers say the man was screaming in Spanish, telling people not to touch him.

"I just thought we are not having another 9-11. Like, this is not going to happen, and I was just so thankful that my husband and the other men jumped in immediately, so he didn't break the second panel of the window. We were using shoestrings and belts, headphones, just to get him restrained," Brown said.

"I was absolutely terrified. I didn't really know what to think. I didn't know what was going to happen to all of us. I was really concerned for my dad, because he's very brave for wanting to do that," Starcevic said.

Passengers say the man appeared to be suffering from a mental health crisis.

What we don't know:

Police did not say if the man was taken to emergency detention or to Ben Taub Hospital.

Since Frontier declined charges, there is no indication anything will happen to the man.
