Mysterious Shards of Glass Strewn Across Miles of Atacama Desert

[Astronuc]

TL;DR Summary

A mysterious field of glass fragments, scattered across Chile's Atacama Desert, and aligned in a vast corridor stretching 75 kilometers long (almost 50 miles).

A mysterious field of glass fragments, scattered across Chile's Atacama Desert, and aligned in a vast corridor stretching 75 kilometers long (almost 50 miles). They first came to scientists' attention about a decade ago.

Twisted and folded silicate glasses (up to 50 cm across) concentrated in certain areas across the Atacama Desert near Pica (northern Chile) indicate nearly simultaneous (seconds to minutes) intense airbursts close to Earth’s surface near the end of the Pleistocene. The evidence includes mineral decompositions that require ultrahigh temperatures, dynamic modes of emplacement for the glasses, and entrained meteoritic dust. Thousands of identical meteoritic grains trapped in these glasses show compositions and assemblages that resemble those found exclusively in comets and CI group primitive chondrites.

I take it this is something that would not be explained by a comet with multiple pieces all doing air bursts?
