Hello, Larry and the list,

in these "shower-cases" I strongly aggree this. The term "main mass" is
useless and also in fact impossible to prove. Anyway I would like to speak
about the largest recovered piece known this far. For example new Sikhotes
are found every day, and no one knows, has the largest one recovered this
far, and if so, where is it now.
