Question to Mxmanic

The wake consists of more than just the downwash you
are fixated on. If you have ever seen a sky-writer at work, you would
know, even without setting foot in a real aircraft, that it is possible
to return to the same parcel of air and pass through the smoke you had
left previously.
I never questioned that.
On a calm day, no descending or climbing is required.
How do you know? What skywriting have you done?
