[meteorite-list] METEOROLOGIST

[Gerald Flaherty]

Hi Chris, I live in Plymouth Ma, I missed the bollide but heard the live 
police, military, and fire chatter on my scanner. The first report came from 
State troopers that had a report from Otis air base on Cape Cod about a 
meteor that was at about 755. If this was headed west it probably made 
western NY or Ohio huh?
