If a comet is to come.
17 cities:
8 cities create main comet vector:
BostonNew York > Philadelphia >Baltimore >Washington D.C. > Charlotte > Atlanta > New Orleans
4 cities Secondary comet vector:
Detroit *Chicago > Las Vegas > Los Angeles
2 cities Tertiary comet vector:
Nashville Houston
1 city Quaternary comet vector:
Miami
Quinary comet vectors:
Seattle : San Francisco
*Possible comet breakup zones. Large explosions, Severe devastation
New York - Main Breakup in 3 parts "Boooom!"
Washington D.C. - Second breakup "BOOM!"
Chicago "Boooooooom!"
I have no evidence to point to this reality. Presented as food for thought. A stepping off point. For Example, Project Blue Beam can project the "comet" not comet as distraction for on going milops in these cities with controlled demo of entire cities(New York, Washington DC, Chicago) as cover.
I hope this doesn't happen.
