Is the National Aeronautics and Space Administration (NASA) trying to hide something from the public, particularly proof that aliens indeed exist?

The space agency is receiving criticisms from conspiracy theorists after a live feed from the International Space Station (ISS) was cut off just as an unidentified flying object (UFO) was seen in the video.

The mysterious UFO, which was glowing blue and horseshoe-shaped, was first spotted by Scott Waring of the UFO Sightings Daily hovering on the horizon of the ISS.

NASA's act of cutting the live video feed while the UFO was in the frame fuelled some alien believers to demand for a significant cut in the space agency's budget for participating in what they called the "great alien deception."

Alien hunter Tyler Glockner, who uploaded Waring's video on YouTube, told The Mirror that it was not the first time that NASA tried to conceal evidence of extraterrestrial life from the public.

"It is definitely another interesting find and once again directly after it appears NASA cuts the feed. That's why you see the screen go blue. They've done this. They have been doing this. They have their hand on the chicken switch as they call it," Glockner said.

"I know they monitor these feeds but sometimes they're not quick enough and UFOs appear. We have documented that on this channel for years now. The only time when the feed tends to get cut is oddly when these UFOs appear," he added.

Glockner is also convinced that what appeared in the NASA livestream was an alien vessel.

"When you play this footage quickly, it looks like the UFO changes its position. When we first see it it's more on its side, but when you cycle through the footage it seems to be maneuvering more on its face," he explained.
