Here is a sketch of a craft observed by at least six witnesses in Youngstown Ohio. No beings were observed but the chairs that were visible through the "cockpit" window appear to be for an adult human. The device was aparently operated by remote control or by artificial intelligence. The device emitted a 25 Hz hum. When it took off it left in the blink on an eye. It was around 40 feet in diameter and hovered around 50 feet above a tree within 40 feet of the witnesses. The tree ( a blue spruce) died shortly thereafter (within 6 months).
@Tastyfrzz I find that fascinating. It appears to be quite similar to human technology, which I would expect if humans had previously colonized other planets, and we here on Earth just had no memory of it due to somebody burning down a library or some such.
