Air Force won't talk about 2 1 kiloton airburst above Greenland base

Roughly 26.7 miles above :Peterson Air force base in Greenland on July 25 some thing exploded with the yield of a miniature nuclear weapon (2.1 kilotons), but the Air Force is keeping a lid on it, only confirming that the object was real. They also said, and this is doubtless a lie, that this did not affect operations at the base. (Bull)
     The fear is that this could have been mistaken for a Russian first strike and triggered nuclear war.
