"Heavier than air flying machines are impossible" I forgot who says that but remember we may no know how things work in this universe. But I always keep an open mind to things. We are freaking drawing electricity from photons from the sun just with a combination of some molecules. Simply unheard of in the infancy of knowledge of electrical applications. Who knows how many elements in the universe, we still don't know about dark matter and energy and it's still theoretical. For all we know, if it is foreign, could be made up of some unknown material. From what my chemistry book said. Hydrogen is so light it actually can escape the Earth gravity. And the opposition force of two electrons is stronger than gravity itself. So...
Surprised no said it was Cosmos, what a shame. Anyways, it's probably just some experimental plane, you know going out for a test flight.
Going by the video that Godziboy1993 posted I'm pretty sure it's a meteor. The fact that the trail is so wide implies that it's moving in a part of the atmosphere where the pressure is low i.e. high altitude. A vapor trail like that would tend to be compressed in the lower atmosphere like the contrails we're used to seeing behind airplanes. Plus the part where it "bursts" implies ablation, that the atmospheric friction is causing it to heat up and lose material. What happened there is that a pocket of volatile gas hidden among the rock or ice heated up so quickly that it exploded and disrupted the trail. Especially notice that the forward end of the shockwave momentarily "outruns" the object; an object propelling itself would not shoot its reaction mass before it. As to its longevity, it could have been a rather large meteoroid that took a long time to vaporize entirely or it was just skimming the atmosphere and bounced back out. Enough of it might have survived to decelerate and land, so the Chinese authorities might be able to track it and find the remains, assuming it didn't go on to fall someplace else.
I wish someone would tell us the Truth about UFO's or whats going on. Remember the one in Norway? YouTube - Norway Spiral UFO Video December 2009 We need Robert Stack to figure this out quick!
This isn't the first time it's happened in China. They also have a similiar roswell incident a few decades ago. Add in the arizona lights, and heaven knows what other events that have been forgotten overtime, and it's not that surprising really. Heck, most people still think earth is only populated by carbon based life.
"b) the same video wasn't taken anywhere near China. It was shot near Kazakhstan. " Doesn't look like a rocket to me though.
I just saw this thing on the History Channel (maybe discovery?) about Foo Fighters. Apparently, either the Nazi's had really advance technology or Aliens assisted during WW2
