It would be also interesting to see the data on Allende, which has a
strewnfield which is 48 km long. Another factor to consider is the
velocity of the object as it entered into Earth's atmosphere.

Peeksill is very interesting because it was an Earth-grazing event.
In other words, if the Earth did not have an atmosphere, Peekskill
would have just flown on by Earth and not landed. But since Earth did
have an atmosphere, the meteor was slowed down enough to land.
The videos of the Peekskill fireball show it breaking up into
several fragments, perhaps as many as 60 fragements. Only one
lone fragment was recovered - the one that hit the car.
