Question for somebody who knows everything:

[Big Tracks]

Yesterday my lovely wife and I were in her car and we commented on some (six or seven) bright contrails criss-crossing a very clear blue sky.

Now, that's not unusual at all around here. One thing we have plenty of is airplanes, both civilian and military, and many are at high altitude so contrails are common.

Later in the afternoon she was making her daily post office run and her cell phone made its annoying noise so she pulled onto a parking lot to answer it.

While she was talking she glanced up and saw this attached sight.

How come? Contrails ain't round. Are they?

Not even the cockiest show-off aerobatic pilot would be doing air show maneuvers (complete with smoke) right there ..... on Friday in the middle of the day? ..... and just a few minutes from DFW airport?

Jerry, you know about stuff like this! What gives?

Would they?
