hey max, this is cool...did you see this?
  This  extraordinary machine was flying at velocities too high to be man-made.  Scientists have estimated the speed, depending on the size of the  object, to be at least 4000 - 6000 mph. Humans inside this object could  not survive. And, somehow, it made no sonic boom, a noise similar to  thunder which occurs whenever something exceeds the speed of sound (750 mph at sea level).
  Astronomer Luis Barrera from the Metropolitan University of Sciences in  Chile, who has an asteroid named after him, was one of eight highly  skeptical scientists who analyzed the footage. He was able to rule out a  meteoroid, pieces of meteors or comets, space junk, a bird or an  airplane.
  "The object performed a risky flight maneuver in  front of the Halcones from W-E-W, at low altitude and high speed,"  Barrera concluded. "It had intentional movements. It moved east with 25  degrees inclination, which is the same angle of spacecraft when entering  the atmosphere."
