[meteorite-list] Rocks from Space Picture of the Day-September14, 2009

[Jeff Kuyken]

Hi all,

Most of you have probably seen it already but for anyone following this 
thread there is footage of a couple of trees in the Sikhote-Alin documentary 
where pieces have gone clean through them. It's at about 6:08.

Cheers,

Jeff
