|low flying, very loud piston type engine, extremely slow moving craft, unseen
The sky was completely overcast, but an exceptionally loud aircraft type engine could be heard at a very low altitude. The craft was passing from the northeast to the southwest at an incredibly slow speed. The engine never changed it's effort and the noise almost hovered in the sky it was so slow moving. No lights or evidence of the craft were detectable.
