On february 19th at 2:47 pm i was driving west in my car on fair oaks blvd. i came to a stop light at howe ave. at that moment i noticed out my driver side window, which was rolled up, a con-trail and motion in front of it. the altitude appeared to be commonly as that seen with commercial airline jets. as i watched it turned nearly at 90 degrees. i immediately reached for my phone to take a picture. it the time i was able to take two images, the object moved a distance which seemed faster than a jet plane at similar altitudes. in my two photos submitted, there is a reference mark at the over hanging street pole. you can see the contrail length increases between the two images suggesting speed. this distance transpired in the manner of time estimated to be within one second. effectively the time it takes to depress the phone's shutter button twice. i would not have really paid any attention to this normally, but what caught my eye was the change in direction from what appeared to be at a very high altitude and rate of speed. one other thing i found odd was there was no visible indication of a craft in front of or attached to the trail.
