We all know about the Chinese spy balloon and are now hearing about cylinder and octagonal shaped objects being shot down. Except for the balloon it's all top secret right now.
What I want to know is: is it purely coincidental that these unknown objects are appearing at the same time the balloon was noticed? Does China have advanced high altitude drones that can spy or are these in fact alien UFO's? If they are alien I have doubts they could be taken out by our missiles based upon previous info from pilots who filmed and commented on their speed and actions. If they are Chinese, Russian, or others, they have some advanced, dangerous (to us) crap flying around.
If we are speaking of 2 different things here: Chinese and aliens, why all the attention now? Have our sky's been neglected till now?
