Two mysterious videos have been recently uploaded on YouTube claiming to be proofs of alien life existence. So, did the latest UFO sighting really reveal that extraterrestrial life is real?

Many viewers were left baffled after watching two alleged UFO sighting clips. One video was caught over Illinois and the other was out of John F. Kennedy International Airport in Queens, New York City.

In Illinois, an Oak Park witness captured a storm cloud in a video. But what was surprising was catching an unidentified object entering the frame from the upper left and moves down and to the right. According to Open Minds UFO News and Investigations, the six-second video published by Mutual UFO Network (MUFON) showed a bright orb that was believed to be a UFO sighting.

"I was shooting video of a storm cloud emitting heat lightning from our back porch," the witness stated. "When I viewed the video I saw a streak of light that I cannot explain or rationalize."

Since the unidentified object looked like a bright orb, Illinois MUFON State Director Sam Maranto and Assistant State Director Roger Laurella are investigating the video.

Meanwhile, another reported UFO sighting was caught on video when a Virgin Atlantic fight took off from John F. Kennedy International Airport located in Queens, 12 miles southeast of Lower Manhattan in New York City. In the clip, a mysterious object was seen racing past the commercial passenger jet as it flew out from the runway.

The UFO/Virgin Atlantic video was published by LookNowTV. Inquisitr noted that the YouTube channel claimed that a flying saucer soaring behind a commercial jet.

In the video, the object was unidentified but NBC News revealed that Delta flight 407 had a "near miss" encounter with a drone at 1,200 feet as it was coming in for a landing at JFK last week. Another drone sighting was also reported by JetBlue flight 1834 just two hours before the Delta flight had its "close call" at JFK Airport.

So, was it really a UFO or just an Earthy-kind object like drones? According to UFO expert Russ Kellett, the video was just showing another plane in the distance. While Scott Waring at UFO Sightings Daily reported that "alien drones" were frequent visitors in airports. But he also admitted that since "the explosion of consumer drones," it has been a tough job to prove that alien drones over airports exist.

As the New York UFO sighting created a buzz online, Examiner reported that JFK airport has become the scene of a few unwanted flying objects. In recent weeks, two planes have reported they had a close call with a drone.
