Wow. Just add it up...

These drones are not exotic enough to evade military intelligence and satellite monitoring. If the DoD wanted to confront and analyze these objects they could and would.

These drones are enormous by drone standards.

These drones are launching and visible while launching, by ordinary citizens.

I therefore believe:

The drones are ours (US's.) I just don't think otherwise.

This is a massive psy-op intended to attract normie attention.

The next big thing is going to be a supposed alien invasion. The drones will be revealed to be our counter measure for alien attack, developed by the US for combat purposes. Or something like that.
