Need to slow dont my imagination....the mental doomsday clock is spinning wildly out of control.
While listening to that, one wonders about all the possible things that it could be including a hoax. But also other weirder ##@%.

Things unknown, and unspoken. Things performed in secret and not for the good of the world.
Yo imagination...Slow the hell down!

I'm starting to succumb to the viral marketing theory. It would be incredibly easy and somewhat ingenious for a marketing company to randomly choose people throughout the world to send them video of people pointing cameras toward the sky and muttering "what f*ck is that?!?", and then overlaying the audio. All for an upcoming alien invasion flick (which are rather in vogue these days). It's certainly building up a buzz - now whether people would be pissed or pleased to find out it's all a hoax for a movie, that's another story...

The other thing that doesn't fit with that theory, though, is the people on here saying they've witnessed the sounds themselves. Unless they're mistakenly associating ordinary (trucks, construction, etc) sounds with what's in the video (which are pretty obviously not ordinary).

Not sure what to think, but sometimes we should listen to our little Occam..
