Nothing more than a failed attempt at penetrating the dome (Raqia) covering the stationary flat earth God created. His footstool, like a tent.
The nukes couldn't bust it "LIKE MOLTEN GLASS" and now focused powerful radio frequencies had no effect, Duh.
Get the accepted flat earth map out and ask why Alaska? Well, it's populated, US territory, just off center of the middle of the dome for great trajectory of radio blasts. Sound will break glass, check out this singer, maybe he should try?
