Sary Shagan was the real subject

This is a CIA intelligence information report from a former Soviet source about the Sary Shagan weapons testing range, including a late-summer 1973 sighting of a green circular object in the sky. The location is the key detail: Sary Shagan was a weapons site, so an odd light there had a possible military meaning long before any cosmic one. The most cautious reading is that its value came from where it happened.
