Here are the first 4 episodes of UFO Hunters Season 4 on the History Channel. I don't know if there will be more.
Thursday October, 29 at 8pm (eastern) / airs again at 12am (eastern) UFO Hunters: The Silencers
"UFOs are the biggest mystery of our time and somebody--or something--seems determined to keep it that way. Hundreds of UFO researchers and witnesses
have told of terrifying encounters with mysterious men, usually dressed completely in black, who threaten terrible consequences if they don't keep
silent. The Men in Black seem to appear out of nowhere, know facts the witnesses haven't divulged to anybody, and frequently display bizarre
behavior, leading some to question whether they are in fact, human. The team interviews men who are only now willing to come forward to tell their
stories. A sketch artist will create portraits of the MIB to see if the sightings match. The team will also analyze the only known photograph of a MIB
and talk to the photographer. Finally, the team travels to "the new Area 51" in the Utah desert, to a site rumored to be the place where the MIB
Thursday October, 29 at 9 pm (eastern) / airs again at 1am (eastern) UFO Hunters: Area 52
"Area 51 is considered the ultimate top secret facility, one that UFO investigators believe houses an extraterrestrial secret. But is there an even
more secretive facility? In Dugway, UT, there is a remote testing facility sometimes referred to as Area 52. UFO watchers in this part of Utah have
witnessed strange phenomena at this military site for over 10 years, leading to speculation that much of Area 51's secretive work is now conducted at
Area 52. The team examines video of bizarre beams of light seen shooting up from the area, meets with an astrophysicist who has charted mysterious
cosmic rays operating out of Dugway, and analyzes photos that suggest something very strange is taking place."
Thursday October, 29 at 10 pm (eastern) / airs again at 2am (eastern) UFO Hunters: First Response
"For decades, it has been believed that the United States military have had unexplained encounters with the UFO phenomena. Our team sets out to try
and uncover the armed forces' "first response" to UFO encounters. They investigate a claim that in Long Beach, California, multiple UFOs were seen
and pursued by military helicopters. They revisit the area of the alleged 2008 UFO crash in Needles, California. Here, it is believed the military
presence has been beefed up as the number of UFO sightings has grown."
Thursday October, 29 at 11pm (eastern) UFO Hunters: Dark Presence
"There's a growing phenomenon of alleged UFO sightings known as Orbs. Witnesses who see the Orbs also report having dreams, premonitions, and a deep
fear. Some believe that the Orbs coincide with earthquakes, while others claim that the sightings are clustered around sacred sites and petroglyphs
that depict the Orbs in ancient artwork. The team will take their investigation to three of the most active Orbs locations in America--Arizona,
Indiana and Missouri--to examine video and talk to eyewitnesses, to unravel the mystery of why Orbs are appearing with alarming regularity, perhaps
directed by an otherworldly intelligence."
