I was standing outside and heard a commercial airliner heading by and Abbi looked to the west of my location I noticed a very bright white light traveling at an extremely high rate of speed from west to east. I had an LED flashlight on me so I began flashing "SOS" in Morse code at it and as it came almost directly over head it began to slow and came to a complete stop. At that time it began to dim in brightness, almost flashing but had no real discernible pattern to it. At this point I continued to flash the "SOS" signal to it and it began to move again in a east bound path, after about two seconds it made an abrupt 90º turn toward the south and then immediately made another 90º turn to head back to the east. During this time there was a commercial airliner to the east of me heading in an E-SE direction . I know this was a commercial jet from the size, sound, and marker lights it had. The unidentified craft made ZERO noise and had NO marker lights at all on it. I have lived near major International airports, Military bases and even local airports so I know what just about anything that fly's looks and sounds like, including ultra-lights,Cessna,Helicopters of all kinds including Black Hawks and Chinooks, Hot Air Balloons, F14's, C130's and so on. This craft was NONE of these. Judging by the altitude of the commercial Airliner I saw I can day that it was most definitely at a lower altitude by atleast half, so maybe 10,000'-15,000' . This is not the first time I and others in my family have seen this object in the past few nights. Thank you for taking the time to check this out, without organizations and people like you we will never be able to find out what all this is about.
