Questions in the Sky part one by Carl Needham

The first words of this book, "The sky is no less blue because the blind man does not see it" (Danish proverb)...   Kauai:  Though occasional heavy jets thunder high over the island the last two days, no obvious trails are left in the sky.  The blue has returned a little more and the visibility has increased.  These things are a welcomed relief for sky watchers.  The sunshine looks more natural when the haze is thin.  I pray it stops for good this time...   Perhaps this book can help decipher some of the many questions folks have concerning this strange phenomenon. http://www.bluenomore.com/Questions1.pdf
