It was about the year 2008, still new to Austin. It was the night before a Christmas Eve & my parents, my son & I were going to the "Women & Children's Shelter" off of 183 & Martin Luther King Dr. to make some donations. None of us have ever been there before & were not too familiar with the area. It was night & the sun had just set so it was still a little light out but getting darker by the second, the street lights were already turning on. The directions to the place were difficult as there were no street signs telling us of any shelters & there were no visible driveways. We later found out that it's kept sort of hidden for a reason, most of these women here are trying to escape violent living situations. Anyways, my dad is driving & my mom is in the front passenger seat. I am behind my Dad & my son is behind my mom & we were in a kind of bigger sized SUV. as we were driving around looking for the streets to turn on (we were at 1 point facing the Austin-Bergstrom Intl Airport, it was about 15 miles away?) My dad points to the lights of an airplane that is hovering & says to my son "Look over there....do you see that airplane? See how it's not moving? It's waiting for it's turn to land." I quickly piped in "THATS NOT WHAT AIRPLANES DO WHEN THEY'RE WAITING FOR THEIR TURN TO LAND! They circle & with each circle they drop a layer in altitude until it's their turn. THAT "Airplane" is NOT circling! THAT "airplane" is not moving at ALL! It's completely still!" My dad stopped & pondered that. He then said "Maybe it's a helicopter?" At this we all recognized that we did not know what the hell that was because none of us could actually SEE anything! All we could see was the lights on it....3 lights that made a triangle. Then we realized that it's not at the airport 15 miles away anymore either! That thing was about 1 block away from us! It came so close so fast that we didn't even notice it moving towards us! Bam! It was just there! It also was only about as high as the tree tops...a helicopter would surely have not flown that low without hitting telephone wires & stuff. My dad kept trying to say it has to be a helicopter. I said "THAT THING HAS NO SOUND! A helicopter is loud as hell...this "thing" is completely silent." (I then realized that the windows were locked so I asked my dad to unlock the windows) we rolled down the windows to listen & there was nothing, not a single sound BUT this thing was now RIGHT IN FRONT OF US! It's about as high as a 2 story house & a little smaller than a house & about as far in front of us as a few car lengths. Still......we can NOT see a THING except the lights that make up a triangle but could tell that the front of it was tilted down at us. The lights were not bright but there were different colors, I can't remember what colors but I do know there was a red one. Meanwhile my mom is yelling at my dad to turn the car around & go down some driveway....as my dad turned the car I scrambled to the way-back to look out the back window & did not blink as I might miss something & I wanted to keep a fixed eye on it, I wanted to just stop everything & watch what I was a part of. As soon as I turned my head to look from the front windshield to the side window to the back window.....it was gone. Completely disappeared. Not a sound, not a breeze, not anything. Just gone. We found the shelter & pulled in to park. My mom asked my dad to help her get the stuff & he looked at my son & said "there's no way I'm getting out of the car!" So my mom got out herself & started walking in. I said "you can't let Mom go out there by herself! I'm going with her!" & I quickly ran to catch up to her. My dad said "I'm not staying in the car alone!" & he & my son ran inside...they practically ran me over. My dad was in the air force & he says he's never seen anything like that before & has never heard of anything in the military like it either. My mom refuses to talk about that night & my dad doesn't either. It's kind of hard to say that we SAW something but it was invisible without sounding really crazy but that's what we saw.Me, coming from a career in optics tried to contemplate the idea for a few years (before giving up on the idea) that we put anti-reflective coatings on eyeglasses to eliminate glare & make glasses look "invisible" every day. Maybe the military has a new high tech type of coating that they can apply to aircraft to make like an "invisible & mirrored" coating to camouflage. Kind of like a movie screen where what we would normally see on the other side of the craft is somehow projected onto the side that we do see so that it seems invisible? But that does not explain the speed at which it was upon us nor the complete lack of any sound or air movement from it. The speed itself was like it was on us before I even had the chance to complete my thought. I just haven't been able to find any reports of any other sightings of anything like this. Also the fact that it KNEW that we saw it from about 15 miles away & zeroed in on us. How did it hear us? Or maybe it didn't "hear" us....maybe it knew our thoughts & was attracted to us by us being attracted to it? I just don't know.
