Re: Spy Stations catch the sound of falling space rocks.



       Abstract from: New Scientist, January 11, 1997 v153 n2064 p180

ABSTRACT: Sound detectors designed to spy on clandistine nuclear 
explosions can detect and locate the explosion of large meteors in the 
atmosphere. Los Alamos National Laboratory in New Mexico measures the 
audible low frequency rambling of meteors crashing into the Earth's 
atmosphere. The estimates of direction recorded by many detecting 
stations provide information regarding the exact location of the bolide. 
The sound detectors are useful for scientists investigating on meteors. 
However, dashing meteors are too fast to let the detectors provide an 
early warning
