Hier “erzieht” die NASA junge Leser, was sie am Himmel zu sehen haben. Die nachfolgenden Bilder sind keine Chemtrails, sagt die NASA, sondern Contrails (allerdings “persistent”). Wenn man jemals nachweisen wollte, wie uns sie NASA belügt, so wäre dies ein gutes Beispiel.

|Many Persistent ContrailsThis photo was taken by Lin Chambers in 1997, right outside the S’COOL office at NASA Langley Research Center in Hampton, Virginia. It shows the extensive build-up of persistent contrails resulting from our location along the East Coast flyway.|
|Contrails AdvectingThis group of three contrails was captured by Ed Donovan of Berry Shoals Intermediate School, on January 28th, 2002 in South Carolina. It shows a series of contrails formed by planes following a very similar route, but then being advected to the left by upper level winds. Note that the leftmost contrail is the thickest, suggesting it has been forming the longest, while the rightmost contrail is still quite thin. Also note that the apparent convergence of these contrails is likely attributable for the most part to perspective.|
|Contrails and Cirrus cloudsThis beautiful display was captured at sunset also by Ed Donovan of Berry Shoals Intermediate School, on January 28th, 2002 in South Carolina. Note the delicate structure in the middle contrail, which results from local air motions induced by the airplane.|
