The Dark Gray Cube Inside a Clear Sphera

Ryan Graves, former Navy fighter pilot and an engineer described one of these things. He he's quoted writing for Politico on February 28th of this year saying that he experienced seeing a dark gray cube inside a clear sphere. The board is just floating motionless in the sky and his his I don't know if he was an F-18 or what he was flying in but he and another pilot flew right past it and almost hit the thing. It's probably doesn't sound like a craft actually it could be or maybe it is. But you know, yeah, that's a good hypothesis actually.
