Has anyone ever seen a futuristic looking silver helicopter or similar that is capable of moves that are helicopters are not?

I experienced this in June of 2019. I saw a spaceship as well when I was about 7th grade. So real I called my mom at work to tell her.

My friend says he's been as far as kidnapped by aliens. We both have bipolar disorder. we both also see and feel spirits. I've always wondered if our disability contributes to us seeing things like that.

The June of 2019 occurrence happened with this friend. we both saw the same thing and neither of us were manic, both medicated. we were sitting on the front stoop of my house. I said Brandon I know the spirits are real, but is there something you could point to that says aliens are real? He suddenly grabs his ear screaming in pain. Then he goes there's the aliens jumps up and and runs down to the street. I follow and we both watch the same futuristic helicopter. it was swooping up and down behind my neighbor's house three houses down across the street. But behind one house. I've never seen anything like it. We walk back to the stoop and there's a sonr playing that if never heard before called "in one ear" by a band cage the elephant. Weird

The house was approximately a block of a 3 lane 50mph road and it's 5pm. Nobody else saw this?? Why?
