Say hello to Geoffrey Forden. Forden is from MIT and he's a weapons expert. He decided to examine the videos and pics. He threw out ones that were shopped. What was left, he has come to a firm conclusion.
The UFO is likely a DF-21 Chinese ballistic missile. His examinations conclude it was fired from around Jiuquan with a trajectory for the eastern Gobi Desert.
Hmm...missile launch...nearby airport closed down until coast is clear...it fits.
So, not exactly a fake. Just not what everyone thought it was. Science marches on.
