Black 'cube' UFO over El Paso -- the work of aliens or a hoax?

Two El Paso residents have reported seeing a UFO in the form of a black cube.

According to Secureteam10, an online entity that posts YouTube videos of purported UFOs and similar phenomena, the cube was seen about mid-day June 29 in El Paso by two people.

A man who was leaving his office about 1 p.m. for lunch said it began to get very windy and he noticed that the center of some swirling clouds became "jet black," Secureteam10 stated in a video made from photos the man took.

Just as the man snapped the photo, a massive, cube-shaped UFO appeared, "jetting out of this worm-hole type manifestation," the video narrator said.

"I am personally at a loss for words because this thing is mind-blowing," the narrator continued. "Not only do we not know what it is -- Is is it a craft, is it an entity from another dimension, is it a probe sent here from a higher intelligence in another galaxy?"

A woman who works as an accountant at an El Paso office also reported seeing the cube, which she described as "sinister," in a telephone interview with Secureteam10.

"It stopped me in my tracks completely," the woman said. "I remember a magnetic humming sound that emanated from this thing. It was really scary."

But Fletcher Gray, the head Texas investigator for the Mutual UFO Network, said he believes the video is a "computer generated image," or CGI.

"If you blow the thing up, you can see too many pixels," Gray said Tuesday. "Someone is playing a practical joke."

In a telephone interview with the woman who claimed she saw the black-cube UFO, Secureteam10 asked her what she would say to skeptics who call the sighting a hoax.

"All I can say is I was there and saw this thing with my own two eyes," the woman said. "I personally took a picture of it.... I hope that my doing this interview can confirm this did happen. No one is going to tell me different, for sure."
