(CNN) - Lovers of conspiracy theories again point to the NASA space agency say that conceals the existence of extraterrestrials.
A live webcast of the International Space Station, which has a constant signal through internet- appeared to show a UFO, and then the transmission was suddenly terminated, they say.
The screen was turned blue and out over an hour.
It may be coincidence, but for many it is strange that NASA has cut transmission after it appeared an unidentified object.
Some point out that it is extraterrestrial.
The UFO was identified by Scott Waring UFO Sightings Daily.
Then Tyler Glockner, an expert on these theories, posted a video on his YouTube channel that has become viral: already more than 220,000 visits.
Tyler says another transmission was also cut in 2014.
It is not a minor theme. Even Hillary Clinton has said that if she becomes president she will declassify the files about aliens.
