Booms are info drops, possibly DECLASS. Or at least, the threat of DECLASS.

Planes being grounded wouldn't be surprising during Great Awakening.

That being said, I'm in the camp where GA will be more gradual. Specifically due to Patriots controlling all the pieces at the end stage we're in.

I imagine a big boom would happen if they hit the ground.

I am about to nap, I swear I better not wake up to news of a terrorist attack.
