In a new video, a UFO seems to approach Mexico's Popocatepetl volcano, then slows down, turns and deliberately enters the smoldering volcano crater.
The video, recorded on May 30 at around 8:30 p.m., is the latest in a series of alleged UFO events that have taken place near the central Mexico active volcano since late 2012.
Watch the video broadcast over Mexico's FOROtv:
Mexico's media company, Televisa, monitors any daily activity around the volcano, which is about 40 miles south of Mexico City. Last November, video images showed what appeared to be a brightly lit, cigar-shaped object plunging into the top of Popocatepetl.
At the time, Marc Dantonio -- chief photo and video analyst of the Mutual UFO Network -- suggested the object was "a meteor captured on successive video frames."
HuffPost asked Dantonio, who creates special effects and is contracted by the U.S. Navy, Congress and the Joint Chiefs of Staff in Washington, to weigh in on this latest video.
"What I think is that this is not a likely fake. I think, for the moment, this is a genuine image capture," he told HuffPost in an email.
"This is a low light camera (which) allows the vulcanologists studying the footage to see any incandescence on the flank of the volcano in night shots. As such, any brighter lights that are captured will appear very bright, as the one planet/star indicates."
Dantonio points out that the camera created a time lapse video of still shots put together.
"When played back at normal video speeds, the object is made to appear to be moving very fast, but, in fact, it is moving at aircraft speeds if you play it at the proper frame rate for the capture."
While he admits the time lapse effect prevents confirmation that the object had wingtip strobes, which would help prove the terrestrial aircraft argument, Dantonio asserts that the flying object "is turning at a rate consistent with aircraft, but the case that it is descending is not at all made. In this case, the object is moving from right to left and appears to be descending, but it is exactly this behavior you see if an aircraft at altitude is heading away from you -- this is the consequence of perspective and round Earth."
While the jury is still out on this most recent video, Dantonio isn't buying that we're seeing an alien craft headed for a hot volcanic bath.
"I am leaning toward the object being a captured commercial jet passing through the field of view. Several elements of this video are initially startling, firstly that the object appears to be moving fast, and secondly, that it appears to be descending into the volcano.
"Because this is a time lapse video, however, the speed is an illusion, and the flight path of the object and the descending appearance are likely an illusion of perspective, as well."

This changing sequence of lights was seen over Warren, Mich., on Jan. 10, 2013, moving in patterns similar to balloons or lanterns.
This is a slideshow of many videos taken by people around the world who happened to be at the right place and at the right time with a video camera to record unusual lights or objects in the sky -- sometimes at night, other times during the day. Statistically, 95% of UFO sightings are easily explained. How many of these videos do you think represent the 5% of UFOs that can't be explained?
