(meteorobs) Meteorobs - skipping meteors -Addendum

[stange34 at sbcglobal.net]

Further thoughts... This may be a contributing factor in the recent New 
Mexico Earth-Grazing fireball of the 13th which entered and left the 
atmosphere at shallow angles of 20 to 25 degrees. Period of visible abation 
changes would also relate to rotational mass of the object and its velocity.
