Chemtrails? in the early morning sky.

When I was working on some research about chemtrails, I found out that it is a world-wide level movement. I have seen chemtrail on the sky in San Francisco when I stayed in Star Motel. In the morning when I checked out, I found a big white X mark above me. If that was done by the air planes from SF air port, there should be more than 2 lines. What made me notice about the sighting is the way the white smog spreaded in the sky. Two lines were at the similar height and the size of the spreading was pretty much the same.

The below is the video of the chemtrail-like smogs I found in the moring around 5:30am on July 2nd. During the day time, contrails are very rare. Just look at the way the smogs are spread and the lines are.
