Huge submarine shaped craft in the sky in Temecula 300 yards wide.I was driving north on Ynez road at around 9:30pm to get some food. From the east appeared two lights spaced from eachother. At first i thought maybe it was two planes flying next to eachother as it got closer the object looked like a giant submarine it then turned north. I went north filled with curiosity about this object and turned right on some road in a comercial area eventualy the object was directly above. Other cars in the area were all driving slow and gazing on up at the sky. I then found the object getting closer and closer above me i looked up and the object was giant probably around 300 yards it was all i could see above me naturaly this is when my fear set in. I then turned a u turned and the object continued north. During this whole event i heard a deep low frequency rumbling noise. After the object left my site i returned home and called my friend. The next day went by and we decided to go out and look for it again. We went out a little later then i had the night before and we saw lights off in the west. Shooting from one area to another with great speed. He then became very excited we drove around the area for two hours but failed to see anything else besides that first initial light. We will be back tomorrow night around the same time with a camera to see what we can. This is the weirdest and possibly the most terrifying/exciting event of my life.
