You are looking at a photo of a sheet from the June 9, 2013, edition of the StarTribune newspaper, published in Minneapolis, MN. Left-hand page is page A8. Right- hand page is page A5.
Notice the advertisement that occupies the bottom half of page A5. It is an airline ad for AirFrance.
The grid of trails in the sky evokes patterns commonly associated with chemtrails, with the ropes from the swings contributing to the aerial coverage. The ad does not include any headline or body copy that references playground activity, vacationing, family travel, or anything to create a context for the kids on swings. They are context-free props, but for the chemtrail ropes. Since this ad ran, the skies over the Minneapolis-St. Paul area have received extensive, repeated trail coverage.
What went through the mind of the graphic designer who laid out this ad, or the art director who approved it, or the agency rep who sold it to AirFrance? It is implausible to suppose that the reference to chemtrails is unintentional. If similar ads appear where you live, you might want to prepare for a heavy dose of heavy metals.
A couple other points:
Such images help normalize a conspicuously hash-marked sky. NASA already is working to shape the perceptions of children, by conflating chemtrails and ordinary contrails. See here: http://mynasadata.larc.nasa.gov/804-2/contrail-watching-for-kids/
A common rebuttal to warnings about chemtrails is that they are equal-opportunity toxifiers, that not even the perpetrators could avoid inhaling the contents of the spays. It might be that through advertisement, the perpetrators signal their cohorts as to where the whammy will fall, giving them fair warning to take a vacation or other leave of absence.
