Things drones can do that seem UFO like: turn sharp corners suddenly and stop on a dime, move in concert as if they were points of light attached to a solid object, disappear or hide by turning their LEDs off, appear by turning them on.

Things drones can't do: go fast enough to cross the sky in a blink, stop on a dime or turn sharp corners at jet speeds, travel at jet speeds at all - without an obvious and loud model jet engine, create slabs of light or opaque surfaces, block the stars behind them like a solid object, be eerily silent.

Eh, if you have an LED screen in the sky, you can create the appearance of a lot of things.

True to some of those (I think that some of the aerodynamic feats can be perspective and size) but I'm not saying "all UFO's are drones" - that'd be ridiculous, just as I'm sure you're not saying that all the claims are real, and the more extraordinary, the more reason to doubt the claim.
