When i was smoking a sigarette (i cant smoke inside anymore because of the law, Damn)
and i saw this line across the sky. It staid there for about an hour and then dissipate into
thin air. The wierd thing was that there was a plane that crossed this line on the same
height had its condensation line disapeared almost imidiatly (spelling? any mods...?)
What do you think......?
BTW - This picture was taken in Haarlem, The Netherlands.
