Meanwhile Martinez, who works as a marketer and strategist n Dallas, was recording what he thought could be his last moments on Facebook Live.

His post reads, " Something is wrong with our plane! It appears we are going down! Emergency landing!! Southwest flight from NYC to Dallas!!"

He then explained that a plane window had blown out: "Engine exploded in the air and blew open window 3 seats away from me," he said in the post.

After safely landing on the ground, Martinez quickly uploaded several pictures of the aftermath and of the damaged aircraft.

"We were probably going down for 10 or 15 minutes. And, of course, everyone is freaking out, everyone is crying. It was the scariest experience," he told CBS News.

"I thought it was going to be our last few moments on Earth."

Martinez also told CBS News, "Once that window exploded and to see the flight attendants all crying we knew that something was really bad."
