Angular UFO sighted as a child

When I was approximately 5 or 6 years old (around 1956), I was playing in a field adjoining my back yard with some neighborhood playmates. My attention was drawn to a white object that was floating in the sky, and coming toward my playgroup. It eventually began descending, and being unafraid of it, I walked toward where I thought it might land.
It came down close to a backyard neighbor’s trash/burn spot as I approached it. As stated previously, it was white, very angular (like a fold-up paper airplane), and floated silently.
It came down within 5-6 feet to the ground. I approached it to touch it, and it gently and silently rose and gradually floated out of sight.
