On my way to the hardware store for some more supplies and snapped these shots. A standard flight going overhead at 13:46 St. Cloud
And to give everyone an idea, by midday the cirrus clouds from the unidentified planes accumulate so the distance you can see standard contrails is limited to less than 20 miles. I took this shot as he went into this haze and never appeared again, due to the slight delay in the camera you can no longer see him as he disappeared in the center of the screen.
This also would explain while on our way to the North Dakota border we can not see any of the commercial flights even though they appeared to be very close.
