It was warm and sunny out so I had just went outside to sit at my patio table and talk to my sister who stopped by. I happened to look up towards to hills and saw a pill shaped object moving across the sky. I stood up because I was going to get my camera but hesitated because the object was moving too fast. It was either white or some type of shiny silver, I couldn't really tell. I was shaped like a gel capsule. Next thing I knew it was gone. I tried to get my sister to look at it but she just glanced and said she didn't see anything. I know it was not my imagination! Never seen anything like it before. Next thing you know it was gone. I'm not sure if it went behind a cloud or if it was too far away for me to see anymore. I've seen many planes and helicopters so I know it wasn't them. It was definitely the length of a large plane but fatter.Thank you for your time and consideration.
