Flying wing shaped aircfaft silently flew overhead, no jet trail, no lights during broad daylight in Massachusetts.Hang-glider or flying wing shaped aircraft that was solid black silently flew overhead on a clear and sunny Saturday. There was no jet trail behind the craft. There were no lights seen on the craft. It was flying as high as commercial jets fly and it was approximately 1-1/4” at arm’s length. The craft smoothly moved from east to west. I was the only witness and went inside the house to sketch it.
