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.)

Hummm,,, Strikes the ground at up to1000kph and not a single fireball
or sonic boom report? Is this a new twist to the current wisdom about
meteorite producing events?
