This is a typical example of a high-flying fastwalker moving across the sky. Sometimes YouTube hoaxers will video a satellite, then alter the speed of the video. It does not appear to have happened here. The creator of this video provided an excellent description of this videotaping session:

Using a Pulsar Recon 550 digital monocular and a Yukon MPR, what was initially thought to be satellite was tracked and film. You will see in the footage that the first object is quite faint but you can see it moving in a straight line through the shot. Then a second object moving much quicker enters the shot but as it moves parallel to the first object and too the right of it, it suddenly moves away from it. It clearly increases its distance from the first object.

Both objects were moving towards North West. A tripod was not used in this instance, because I am not a specialist and boast about having the best tripods. The one I use is good enough for what I do and is light weight and quick to set up but does not tilt straight up.

(Please note that the time on the footage is one hour behind due to British summer time effect.)

Now these are UFOs because they cannot be identified easily. Satellites move it a set orbit at high speed in space, but cannot just simply 'move away' from another object so quickly. NORAD monitors space traffic and satellite operators are notified in advance of possible collisions so they can adjust the orbit to move out of the way.

But in this footage the object on the right clearly moves away from the first and increases its distance. Is it high altitude aircraft operating in space? Could they be drones? Could they be satellites?

Or are they extraterrestrial?

One of our video experts says of this video, "I have no opinion about this, but it doesn't feel obviously faked." The video shows an object that is maneuvering near a helicopter over an unidentified Irish village. The helicopter and the object are far away, but a close listen to the video does reveal the sound of the helicopter rotors. In addition, the object undertakes maneuvers that can't be carried out by planes, balloons, helicopters or any known form of aircraft.

What could it be? The object could be a simple animation. It's too far away and too low res to be certain. It could be an insect much closer to the camera, but this seems far-fetched. Our verdict: possible unknown.

The story of Robbert van den Broeke is one of the great enigmas of paranormal research. A great deal of the phenomena he reports, often leaving strong evidence in the form of crop formations near his home in Holland, photographs, and multiple witness observations, is verified. In this video, members of his family describe their own experiences with the phenomena he has been witnessing and reporting for years.

This UFO video from Arizona appears to be a triangle UFO, with which Out There readers are very familiar. Of course, it could be a delta winged aircraft of some sort. It's hard to see until the third version of the clip, running at 0.65 of normal speed. Probable unknown.

Our first expert has said the following:

The tracking miss at 1:32 bothers me. This looks poorly tracked where as the rest is very acceptable.

Not sure but I think it is a fake.

Our second expert says this:

What looks like a tracking error at 1:32 actually appears to be a shift in the shooter's perspective. He steps to the right, which momentarily changes the relationship between the camera, the tree, the bushes, the houses, and the lights in the sky. This move is preceded by a very natural-looking jiggle of the camera.

So on the level of tracking, and of the realistic appearance of the overexposed (blooming) orbs as they are obscured by various foreground objects (which would be pretty damn laborious and time-consuming to fake, though certainly doable), I'll give this video high marks.

To be clear, this vid COULD be real.

It COULD also have been very carefully made and then deliberately degraded to hide the seams. Some of my doubts are fueled by the following:

- A YouTube description utterly devoid of useful information.

- No audio. This would make some sense, because if a hoaxer hasn't planned out all the "ooh" and "ahh" moments in advance, said hoaxer would then have to produce a credible soundtrack, which may or may not be within the scope of his technical repertoire. .. and which, as we've seen before, is extremely difficult to fake. Being a whizbang with the visuals is one thing, but creating a technically and psychologically convincing soundtrack is quite another.

- These orbs appeared in just the right spot (between the houses) to be seen by the shooter, and continue to appear in the right spot each time. They're perfectly framed for the camera, and they conveniently change direction to remain between the houses as viewed from the shooter's perspective.

- Said shooter seems to have had zero curiosity about these thingies once they went behind the bushes. One would think that, at least following the final orb he'd have attempted to zip around in front of those neighboring houses to see if he could catch a  further glimpse of these things.

- And finally, Cork is a big city, yet so far no independent reports have surfaced.

I went to the YouTube page of the guy who was named as the source (Natkis Ireland) and saw the unstabilized version of the video. No detailed info there, except that he says he has a better camera but claims he wasn't able to deploy it quickly enough so he used his cellphone. He sounds like a sober chap, and his YouTube home page isn't full of other UFO videos, though he does subscribe to an ET page that seems a little iffy to me. (http://www.youtube.com/user/1967sander).

I can find no evidence that he personally possesses the skills to have faked this video. On the other hand, a skilled confederate might have been involved.

Our third expert says:

I'm going to come down hard off the fence and cry "foul". This event, if real, would surely have drawn not only media coverage, but also other videos from different locations (how much footage was there of the meteorite?). It's a big city, it's not dark, they keep on coming ( a bit like a big lantern release would) and as Dan says, very conveniently emerging from the gap between the houses.

Your Out There editor's opinion:

Two of our experts don't rule out the possibility that these lights are unknowns. The third feels sure the video is a hoax. I think that this could have been made by releasing sky lanterns, then opening the shutter of the camera to make them appear extremely bright. However, there is no way to make a final determination with this video. Possible unknown.

This video from April 14, 2013, is hard to evaluate, but the videographer, who could, of course, see more with the naked eye, appears convinced that it's one of the Lake Erie UFOs, and we are getting reports from others that orbs are being seen over the lake nightly.

This may be a genuine unknown, and if so, it is an excellent UFO photo, reminiscent of the images taken by Ed Walters in Gulf Breeze Florida in the 1990s. There is a possibility also that it is some sort of hot-air balloon, which is suggested by the flickering flame in the base, and its slow trajectory of descent.

This video shows a very fast moving object rising from right to left out of the right corner of the frame. At 40 seconds, the poster provides a slow motion repeat of the image that shows the object clearly. It is not a bird or plane, and does not appear to be a photoshopped. Probable unknown from South Texas, which is in the midst of a UFO flap.

This video posted on YouTube by truck driver Ronnie Dawson of Coleman Texas shows clips of a UFO that he took with a phone camera. This appears to be a credible case, and we are investigating further.

On January 28, a bolide, or large meteor, streaked across the US Northeast. Now, on March 25, another similar meteor has been seen from Maine to Florida. In neither case did the objects cause any damage, but they may be part of an unknown shower of large meteors which has been affecting Earth, which includes the large Russian meteor of February 15, which exploded in the atmosphere with the force of 50 Hiroshima sized bombs.

While some effort has been made to identify asteroids that may be dangerous to Earth at some point, these objects are not asteroids and cannot be tracked as they approach our planet. There is no way of knowing how many more may be out there, or when or where they will strike. Large meteors such as the one that struck in Russia are extremely rare. This was only the second such strike in a hundred years.
