I was laying by pool and looking up at how pretty the clouds were. I watch the planes come over us all the time. Well, I noticed a black tiny version of a plane. Had wings just like a jet real high but quiet and didn't leave that trail of smoke at all. The sky was clear and I watched this plane go through a tiny cloud and disappear! Seconds later a tiny green light came out of the cloud and flew the other way slowly then disappeared. This was unbelievable because the clouds were tiny patches and the rest of the sky was clear. There's No way that wasn't a ufo unless we have solid black jets that in a second can transform into some tiny green light craft.
