Do meteors change direction during re-entry?
Found an interesting Brazilian video on YouTube:
http://www.youtube.com/watch?v=cjuReliyduI
The video has the appearance of being genuine, but I'm not sure about how a meteor would change direction during re-entry. Is there anyone available who knows anything about physics to debunk this UFO?
Explanations in hard science would be preferable to "yeah, it's definitely a UFO" or "it's totally not a UFO" responses. The best explanation wins! (I'll be running the possible explanations past a friend who's an astrophysicist, just to keep people on their toes and make it realistic... and he says no, meteors don't change direction during re-entry, and I haven't shown him the video yet.)
UPDATE: Astrophysicist friend says it moves like a helicopter, and is likely napalm being ignited and dropped. I've never seen napalm dropped from the air, but it makes sense... just didn't see a reflection from a helicopter (which is odd). However, why would it burn napalm that never touched the ground?
What, none of our die-hard skeptics are immediately responding? I'll extend this a few days and see who answers.
Napalm is essentially jellied gasoline. I'm not giving a recipe here, but all you need is starch and glycerine in a specific combination to stabilize gasoline, and you've got napalm. Anyone with any background in chemistry can make it easily.
The wires idea is good, but astrophysicist friend says it would melt and a fuel source would need to be added, as (he estimated) that nearly 1 kilogram of napalm was burned per second to get an effect like that, which would require something far more heat-resistant than the titanium wires that are being suggested.
Been looking closely at the high-quality video, which I downloaded and am looking at frame-by-frame... and it's just not HD, so it's difficult to see much. I was hoping to see a wire or a reflection, but I see nothing.
What I did see, however, was the spot where whatever it was dropped, and the second piece didn't burn for a few seconds... that's suspect. Can't say what it is, but it's definitely starting to shape up a little.
I can say with assurity that the cameraman was not involved in the hoax.
The comment toward the beginning where everyone laughs a little, translated to English: "Look, it's Santa Claus coming to give presents!"
Listened to it again for the helicopter... no, I don't hear it. What I do hear is a car motor (which I can definitely say is a car, and not a helicopter) and normal traffic noises.
I'm liking the helicopter explanation, myself, it's just that I don't have proof.
Oh, and... this is the original poster, and the sound quality is MUCH better.
Still no helicopter. The original video:
http://www.youtube.com/watch?v=PsSG4k0xyLo
The author didn't know what it was, and confirmed that there was no sound of a helicopter. However, helicopters in that area might be baffled (meaning "heavily muffled") by the trees, so a helicopter is still not ruled out, though we still don't hear one.

I would say it is not a meteor.
It would not take that long to descend and it would not remain illuminated for very long once it passed our atmosphere - if it was a meteor.
I suspect whatever it was, had a fire retardent as part of its makeup because it took a very long time for it to disintergrate. It would have to be an object comprised of light weight material for it to change direction so that also compells me to believe it is not a meteor.
I suspect it is a man made craft or satellite.
New note:
In this case it is an "Unidentified Burning Object" so anything could be applicable -UFO -Satellite-Space craft. There were some situations where the government in another country had to blow up their sattelite because it was defective -
Anything is possible :0)

Good video but I would say a hoax. My instinct tells me that it smells of a setup although I must admit I can't see why anyone would go to such trouble to stage it.
I agree with your Astrophysicist friend and other videos I have seen of napalm burning appear much the same. As for not seeing any reflection the helicopter could have been so far above the object that its reflection would not be seen. Don't forget that there are super strong and very thin cables commercially available that could allow one to dangle an object for thousand of feet under a plane or helicopter. It could also be some type of remote controlled drone but unless remains can be found who knows.
To me, the mystery is not that it is extraterrestrial, it is why would anyone bother to do such a stunt as it wouldn't be easy to get the gear together especially the napalm.

So why would Napalm be dropped from the sky and lit?
If a forest area were to be burned for crops or housing, Napalm would be more effective at lower altitudes.
That is a strange video.
And I even looked around for crash sites of satellites and came up empty handed.
What ever it was, it had a fuel source, almost like phosphorus mixed with water.
Then I went to find the chemical compounds of meteorites and found everything but the information I was inquiring.
I wonder if any of the burnt debris had been located to verify what it was?

Absolutely. All it takes is a slight nudge in deep space and the object will move off in another direction. f = ma means the velocity could change direction as well as magnitude in response to that nudge, f. But, that business about objects not changing directions we see all the time in class B sci-fi movies, is about meteors that have entered the pull of Earth's gravity field and are flying inbound to the planet. Those are unlikely to change direction once they've been grabbed by Earth's gravity because it would take more than a nudge to change it. Meteoroids may blow up and shatter; so their bits and pieces might drastically go off in some other direction. But if it remains intact, a meteoroid will not change direction and shoot back up from whence it came. There is no force that would cause that.

I've seen exactly that same thing, but my phone has terrible low light ability and I couldn't capture it. I saw it as I was watching fireworks from my backyard. It occurred at nearly directly above me and so was not a firework. I thought it was a meteor fireball at first until it made a 90 degree turn. I remember a kind of fizzle sound as it went through the air. It was definitely fairly high up. It was definitely unidentifiable to me, although this video shows something like it that was way closer than I could see it.

Well lets see Red..That vid was cool. I think that perhaps pieces of the meteor broke off and went into different directions, as some of the pieces ran out of fire and just fell to the ground maybe. That video stumped me, my first reaction was a firework again but that was way to damn big to be a firework. Anywho, nice catch!
Damn now I'm so confused...lol...Napalm why would that even happen? Perhaps some experiment that we citiznes are not supposed to know about. Here's a website about Napalm:

But still very interesting!

I'm not an astrophysicist but I know that meteors don't fly like that. However if you listen carefully you can hear the helicopter over that annoying whine. Its a cool vid though should be on the SiFi channel.
Yeah I like the helicopter explanation.

Intresting video, I agree with CIA and am absolutely stumped.
EDIT: Maybe they are just not on their computers 24 hours a day.
