I was outside lighting up a smoke and notice this flash north of Venus and almost just as bright and it was just left of the constallation(?-square shape) in the lower north sky. It happened at 6:40. It was clear and brisk out. A small plane was flying just below this and heading towards my house. Then 2 minutes later while combing the skies,opposite in the sky I noticed a single light traveling slightly faster than a jumbo jet coming from the mountain range of La Honda/Pagemill Rd. going towards San Francisco. After it was just about out of my sight the neighbors dog barked a few times but nothing outrageous/mellow like. Then less than 3 minutes after that, I looked in the opposite direction on the other side of the sky close to the initial flash location, flying at half the altitude that I saw the first moving light (which was probably at around 10,000 to 20,000 feet or higher)this one was estamated at around 6,000 may be a little less. I did grab my binoculars and caught a glimps of the first one flying away from me. But I got good look at the second one and to say both had no sound,not even a delay sound as high flying planes have. The second light was pointed in a sort of downward direction and traveling may be 2/3 the speed of the first one. Just after loseing sight of the second ufo/light a large jumbo jet coming from the north and low had all of it's light's on and looked like a christmas tree. It was banking pretty hard and headed for one of the three major airports in the bayarea. This was at 6:49. I heard it's landing gears open and the engines roaring and also the neighbors dog started barking but only briefly. So what was that other stuff? This stuff has happened more than a couple of times. That flash keeps happening the same location...may be it's a porthole or something!
