[meteorite-list] How far away can a meteor be heard?

[Gary Fujihara]

Aloha Bernd,

Thank you for the data on Peekskill.  If memory serves me correctly  
Peekskill exhibited an extended luminous phase due in part to a  
shallower entry angle into the earth's atmosphere.  This PA fireball,  
from video footage, appears to fall at a steeper angle and therefore  
should cover a shorter groundpath.  Best of luck to all in the field,  
and happy hunting!
