I had just gotten home and was walking into my house. I was looking up at the moon in the sky. It was still day light with the sun shining. After I noticed the big moon in the sky I noticed a white jet fly under the right side of the moon leaving chemtrails when I noticed a large very white object flying perpendicular to the line of the jet. I couldn't tell if it was two objects or one with a dark area in the middle of it. It was higher in the sky and appeared to fly over the top of the jet and was going at such a faster speed that I couldn't help but notice it. It flew in a straight line and continued until I gave it up since I didn't have any way to record it. I knew that since I couldn't record it all I could do was watch it. I was talking on the cell phone to my sister when I saw this and asked her if she could see the moon from where she was. she said no. I couldn't make out the wings or tail but I could definitely see these on the jet. I heard no sound. either from the jet or the object in question. The darker area was in the middle of the craft. If it had been a plane it seems like the wings would be in the front and not in the center of this thing. I probably watched it for 15-20 seconds. It was still in sight but moving away very quickly when i came on in the house. I have seem strange things and lights at night but never in the day light.
