>>>> Ok then I will break it down for you....
Vapor Trail
Stratospheric traces
Of a transitory flight
Trails of condensation
Held in narrow paths of white
The trail of smoke from the airplane engines that leave a temporary mark in the sky.. in this case the sky above Manhattan
The sun is turning black
The world is turning gray
Images of people leaving the WTC site covered in ashes
All the stars fade from the night
The oceans rain away
From Horizon to Horizon
Memories written on the wind
Fading away like an hourglass, grain by grain
> Swept away like voices in a hurricane
All that smoke and ash like a violent storm
As for the rest of the lyrics, perhaps predicting a world war triggered in the middle east?
