You board the flight and you think your dream Caribbean vacation has begun, only for the whole thing to quickly turn into a nightmare:

Flight 307 was climbing out of William P. Hobby Airport in Houston en route to Cancun on Tuesday evening when the right engine erupted in flames, KHOU reported. ...

"I think I fly once or twice a month and I knew that wasn't normal and so I opened up my window and I'm sitting next to the engine and that whole engine you see like fireballs coming out of it," said [one passenger], who was headed to the Mexican resort with his girlfriend.

"I'm thinking damn, it's gonna go down," Kalisek said.

Looking out your plane window and seeing this is terrifying enough:

In some ways it's even more alarming to see from the ground.

Thankfully nobody was hurt. The plane "returned to the airport to check out a potential mechanical issue," according to Southwest.

"The aircraft landed safely and was taken out of service," the company said.
