Another video of the "China UFO" which suggests that the current media obsession with UFOs is a repeat of the tactic in which space aliens are waved about to obfuscate evidence of top-secret aircraft/spacecraft development. Again this video suggest a hypersonic wave rider type craft, with indications of stage separation. At one point the exhaust changes from a parabolic shape to a true cone, which tells us the object has climbed above the atmosphere. The Aurora concept being tested in the US back in the late 1980s and early 1990s pre-dates the Scaled Composites design for Spaceship one, in which a large carrier craft takes a smaller ship up to altitude, then deploys it for a high speed high altitude exo-atmospheric run. This looks like what we are seeing here.
