A few comments regarding the Las Lomas video.
1. If that's its normal flight, it would be a pilot's nightmare. It doesn't seem to be stable.
2. If it's as far away as it looks, then there are massive, massive forces involved. A structure as large as that appears shouldn't be able to rock that fast.
3. If I were going to try to fake it, I'd make a model painted in muted gray colors, suspend it on a monofilament from a pole, and take a picture of it as someone lifted it and slowly moved it left to right.
Then I'd apply a little blur to the model and some sky to disappear the string, and make the model appear more distant. Hey, it's a smoggy day!
I'd matte out the model as it crosses in front of the buildings to make it appear it went behind. The buildings have nice straight lines, and pretty good contrast against the sky, so making a matte shouldn't be that hard.

That very same day we inquired from the local police if anything unusual had been reported to their headquarters on the first week of August. Even though they did not accept the interview, the stated that nothing strange had been reported for a very long time in that area of the city.
Then, a little further on:
Once more, during our weekly work session, we received news of eyewitnesses to the event. These persons had stepped forward due to the Tercer Milenio broadcast of the previous Sunday, recognizing the object they had seen in the afternoon of August 6th.
So, a busy metropolitan area. Millions of people. Clear, if somewhat smoggy skies.
A huge alien spacecraft flies over. A few people notice, but no one alerts authorities, or calls the police to ask "What the hell was that?" There's no mention in the newspapers. Rocket launches from Vandenberg AFB get more coverage than that in LA, and those are Identified Flying Objects.
Weeks later, a video from an anonymous source, with a cover letter that, as they paraphrase it on the site, seems to have used Penthouse Letters* as its template, is received by a TV station with instructions that it should be delivered, not to the news department, but a UFO entertainment TV show. The UFO TV show transcribes it to a professional format and "enhances" it for broadcast.
It's only
after that video is broadcast that a few people come forward and say, "Oh, yeah, I saw that."

Wednesday, October 1: We traveled to Phoenix, Arizona, U.S.A. to reach Jim Dilettoso, one of the best computerized image analysts in the United States. Dilettoso has devoted himself, on a part-time basis, to analyze UFO images from different part soft the world, reaching conclusions which have made an impression on the scientific establishment. From the first moment that he saw the August 6th images, Dilettoso evinced an interest in the possibility that the object could be a balloon suspended from a helicopter.
However, after feeding the images into a computer to conduct the initial analysis of the Las Lomas UFO, Dilettoso was surprised---as were others present in the laboratory---when the monitor displayed all of the images elements except for the UFO itself. After a few minutes of concern, arising from the belief that the equipment had been damaged, Jim Dilettoso discovered that within the same image in which the UFO could not be seen on the screen, it would appear in its proper place after passing infrared and ultraviolet filters. This led Dilettoso to adjust all of his analytical equipment to another frequency in order to analyze the object's characteristics, a situation which had practically never happened to him earlier in any other circumstance, and which on the other hand, confirmed the veracity of the video presented.
I'm sorry, this is just ludicrous. Pixels is pixels. You can't usefully "apply infrared and ultraviolet filters" to them.
* Penthouse Letters inevitably seem to start out: "I never thought this would happen to me, but...(unbelievable sexual fantasy ensues)."**
Regulars in Conspiracy Theory have come to classify initial posts with this sort of denial as having "The Mark of Woo".
** or so I've heard.
