On Tuesday night, Jeff Holko noticed something in the sky above Grand Blanc Township, Mich., that he couldn't explain, so he aimed his cellular phone at it and recorded two-and-a-half minutes of video.
"I'm not saying it's aliens from another planet," Holko said, according to MichiganLive.com. "There was no definitive shape. It was almost the shape of a wedge or a disk. It almost had no structure to it. You could almost see through the light."
At the beginning of the video, two clear, bright lights are seen moving very slowly in the sky, and by the time the clip ends, a third, quick-flashing light can be seen with the other two.

"The object took two minutes to make its way across the field in the video," Holko wrote in his YouTube posting. "We watched airplanes with similar flight paths much higher and faster cross the field in 20 seconds with the roar of the engines. This was completely silent."
So far, Holko and his girlfriend seem to be the only ones to have reported the unusual lights. But was this actually something that falls into the category of truly unexplained?
HuffPost showed the video to photo and video analyst Marc Dantonio, who has examined many alleged UFO images.
"At the conclusion of the video, I was able to affirm my suspicion and call this an aircraft on landing approach," Dantonio told HuffPost in an email.
"Aircraft on approach will turn on their landing lights sometimes 70 to 90 miles away from the airport, depending on a number of conditions," Dantonio explained. "When they approach with lights on from such a distance, they will very often appear to be 'hovering' as the witness described when, in fact, they are approaching at a reduced speed -- well over 250 mph, but less than cruise -- and take minutes to get closer."
"In this video, the plane appears to be approaching toward the camera more or less, and then near the end, it turns to the right and begins to cross the field of view more quickly. This is very common in these situations," said Dantonio.
"During those last few moments, the belly strobe and one other light are both visible, flashing at frequencies that are quite consistent with aircraft strobe frequencies as mandated by the FAA."
But Holko maintains on his YouTube posting that was no airplane he videotaped.
"This sighting was totally unexplainable [and] it defied basic flight principles. It was way too low and slow to be landing at the airport in addition to going the totally wrong direction," Holko said.
And getting the last word in here on a typical back-and-forth UFO argument, Dantonio said, "My assessment, with near 100 percent certainty in this case, is that this was another commercial aircraft landing light case."
Here are other UFO cases that weren't necessarily unexplained
This is a composite image of how three alleged UFOs maneuvered about in the sky over Melbourne, Australia, in early February, 2013. The final verdict isn't in yet on whether they're birds, aircraft, balloons, bugs or something truly unidentified.
These candle-lit Chinese lanterns can rise high into the sky and are often mistaken for UFOs.
On Dec. 20, 2012, a bright, circular object (pictured at the top of this composite image) was videotaped exploding in the skies above Sacramento, Calif. It wasn't immediately identified, resulting in speculation that it was either an alien spacecraft, military top secret weapon, runaway planet, North Korean satellite, among others. Within a short period of time, it became apparent that this was a weather balloon. The bottom part of this image shows such a balloon as it ascended over Tampa Bay, Fla., on July 2, 2012, and exploded in an identical manner as the Sacramento object, probably much to the dismay of all true ET believers out there.
This is a composite of images shot by two eyewitnesses of a boomerang-shaped UFO they reported seeing over their Burbank, Calif., home on Oct. 5, 2012. Mutual UFO Network photo/video analyst Marc Dantonio concluded the object was likely "a balloon, floating on the wind that has collapsed in half."
This four-image series of lights in the sky was recorded over Warren, Mich., on Jan. 10, 2013. The lights were seen changing into several patterns. The most logical explanation for these types of UFOs is a series of balloons or lanterns.
This composite image shows four different times that alleged UFO were photographed above Earth by either space shuttles or the International Space Station. The big question is whether or not they are truly unidentified objects or if they are more likely reflections from spacecraft windows, meteors or fast-moving spacecraft-generated debris.

On the night of Sept. 28, 2012, a group of strange-looking lights appeared in the sky near Cincinnati, Ohio. First there was one, then, two, then three lights, slowly descending. It turns out, however, that these lights were originating from a group of skydivers performing a pyrotechnics jump at the La Salle High School homecoming event.
Some UFO sightings may be due to a natural phenomenon known as sprites, like this one shown from 2006. "Lightning from [a] thunderstorm excites the electric field above, producing a flash of light called a sprite," said geophysicist Colin Price.
Clouds: Saucer-shaped or "lenticular" clouds that form at high altitudes have been confused with UFOs.
Blimps or advertising balloons: These can look like flying saucers from some angles, especially at night.
On June 19th the Swedish-based diving company Ocean Explorer discovered something they've never quite seen before. They were exploring in the Baltic Sea between Sweden and Finland looking for sunken treasures when a very unusual image suddenly appeared on the sonar. A 197 feet diameter cylinder shaped object was discovered at the depth of approximately 275 feet which resembles the Millennium Falcon from the movie Star Wars.
An image released on June 15, 2012, shows a close-up view of the unidentified object sitting on the bottom of the Baltic Sea.

Pictured is a quad copter -- a deliberately manufactured UFO created by special effects wizard Marc Dantonio for a National Geographic special, "The Truth Behind: UFOs," which aired in December 2011. On the left is what the small device looks like resting on the ground, measuring 4 feet in circumference. At right, is how it appeared behind a tree in the night sky.
In February of 2012, this fireball was captured by a Texas police chief's A dashboard camera. F.A.A. say this was probably a meteor, falling to Earth. .
Meteors: Space debris can create a spectacular light show when it burns through the Earth's atmosphere, and sometimes reported as UFOs.
Civilian or military aircraft: Planes can look mysterious at night or in certain light conditions, thus confusing an observer.
