Some air travelers were given the fright of their life when a serpent slithered into the cabin of a commercial flight — and no, it's not a scene from the 2006 thriller "Snakes on a Plane."

Passengers on the Aeromexico flight 231 to Mexico City from Torreon, a city in northern Mexico, watched Sunday as a 3-foot-long snake appeared behind the plane's overhead compartment and dropping into the cabin.

"I was reading a magazine and the passenger next to me saw it," Indalecio Medina, who recorded the whole debacle, told the Associated Press.

He said passengers sitting immediately below the vicinity of the snake between rows 5 and 6 quickly unbuckled themselves and cleared the rows before the reptile dropped to the floor.

"It was a frightening situation," Medina said, "but people remained calm because it didn't get out of that space and nobody became hysterical... nobody got carried away."

Passengers were able to trap the snake using blankets provided by a flight attendent, he said.

Aeromexico later joked on their company's twitter page, "No, Quetzalcoatl (a feathered snake god in Mayan folklore) did not come to life."

In a press release, the Aeromexico reported the snake was harmless, and appears to have come from Mexico's southeastern region.

After the two-hour flight was given priority landing in Mexico City 10 minutes later, the airline called local animal control authorities to handle the stowaway snake, according to the press release.

They are still investigating whether the serpent got aboard the plane itself, or escaped from the luggage of a passenger.
