Boing Boing: airplane exhaust scars
by Decius at 10:33 am EDT, Oct 13, 2004 |
Today's Astonomy Picture of the Day that shows plane
contrails like scars across the SouthEast. NASA is running
a count the contrails program for kids over the next two
days. |

Am I missing something in that picture? Those look like high altitude cirrus clouds to me or ice crystals.
I don't see a single contrail. :::conspiracy mode::: (You know what Art Bell says about contrails, don't you?)::::: :) Decius wrote:
