[meteorite-list] Rare Meteorite Strikes Roof in Norway

[Chris Peterson]

I think it is very likely that the majority of meteorites are not 
preceded by fireballs, or not by particularly impressive ones.

There is a difference between the well supported assertion that most 
slow, bright fireballs produce meteorites, and the unsupported assertion 
that most meteorites derive from parent bodies that produced substantial 
meteors.

(There's no way a stone this size was traveling 1000 kph when it 
impacted; maybe a third of that at most. Not that the terminal speed is 
relevant to any details of the meteor event, however.)
