One evening in Ontario California my mother, my brother, his girlfriend and I were taking our dogs out to go to the bathroom. At this point in time we were homeless and living in a tent city that was just north of Ontario international airport. As we all were walking around outside of our little encampment we all seemed to turn our attention to the skyline in the south west.I don't know how to explain it other than It sounded as if something in the sky that wasn't there suddenly in a fraction of a second was.Like it popped into the sky.The day was normal clear sky no wind.All I could hearvwas the sound of something cutting through the air at an unbelievable speed.Kind of a whooshing sound it seemed to come north towards us then change direction back towards the airport,then back again towards us. Just off to the left hand side of us where a couple of dead trees that had no leaves on them.The branches on these trees began to whip back and forth at almost 90' degree angles. The sky above us seemed to be distorted and wavey and you could feel the presence of this huge object you could feel it in your body if that makes any sense. Mind you our location at that time was in an area that commonly has high winds at times up to 70mph on rare occasions. We never saw these trees do what they were doing that day.There was no feeling of wind no dust being kicked up it wasn't until the event was over I recalled noticing the powerlines above the railroad tracks not 100 feet from the trees weren't swaying.I'm pretty sure the area we were in was "restricted airspace" as we could watch the jet takeoff and land at the airport.You could feel that there was something enormous in the air above us but could see nothing except like waves coming off hot asphalt.This all happened pretty fast the object shot over our heads towards the north west.I remember there was an old man named Ken in the camp next to us sitting in his lawn chair he looked at us with a funny look on his face and said "what the hell was that".Now I consider myself to be a sane fairly smart man I understand the possibility of atmospheric anomalies and other wierd things that might be possible.However this event was special I know there was something there,we all expieriaced this...thing that happened I wish so bad I new it was going to happen so I could've made other observations but those trees never moved like that again that sound that feeling in my body never happened again nothing should have been in the air that day certainly not going back and forth changing direction.We know what happened that day was something not everyone will ever experience.Thanks for reading this I told everyone that would listen keep up the hard work.
