I have seen three things in my lifetime that I am sure were not from this planet. The three things I saw were things in the sky that I could not explain. The first two occurred at night in 1970. They only amounted to lights in the sky, but I will never forget them, as I will explain. Two friends witnessed the first sighting and one of the friends witnessed the second. The third event happened during the day about 15 years later and was seen only by me.

The sighting was in Houston.  My two friends and I looked up one night and saw a star-like light crossing the night sky.  We thought it was a satellite, so we watched it.  After traversing across about one half of the sky the object changed directions by 90 degrees.  It did not turn.  It did not slow down.  It simply changed directions.  One instant it was traveling thousands of mile per hour in one direction, and the next instant it was traveling thousands of miles per hour in a direction 90 degrees to the first direction.  It finally went out of sight over the horizon.  The three of us commented about it.
Date is approximate.  Witness elects to remain totally anonymous.  PD
