Anon speculation, probably not accurate but here it is.

Been thinking about this. Remember in March of 2020 when the Empire State Building was lit red with a spinning siren on its mast? It was explained as a tribute to first responders, but always seemed more like a red alarm.

Then yesterday the Fly Eagles Fly posts from Chelsea Clinton, Jill Biden, and the official Empire State Building Twitter account.

Elon Musk also tweeted the Omega (end) symbol, and the timestamp synced to a Q drop referencing the end of the op.
