Alaskan coast, Michigan and Canada are the locations of shoot downs. There is not enough information so far to be overly concerned. Perhaps the worst outcome could be leaving the fate of humanity in our own belligerent hands, but there is as of now, no legitimate reason for concern.

The power of evasion has always been a part of the ufo phenomenon.
Lets hope if there is a 'they' we both will learn something.

Shoot first and ask questions later is a primitive response.
