Last night while lounging on the sofa and reading articles on my laptop, in a house as quiet as a tomb, I was distracted by a strange sound outside. It was a loud rumble like thunder, or a very low flying jet or a large tractor trailer carrying a heavy load going down the highway. I wasn't sure what it was because it really didn't sound like any of those things. What I heard was a low, loud rumble as if a jet were flying over and then instead of the sound trailing off as usual, it just stopped dead. It sounded as if the plane were hovering directly overhead. I thought it was odd but went back to reading.A few minutes later, I heard it again... same loud rumble and the same weird abrupt end to the noise. Ok, so now I'm thinking, that IS really odd. I ran to the backdoor and opened it and just listened. All was quiet so I listened to the traffic sounds. I heard the normal whoosh of the distant highway, nothing unusual there. By now I knew I hadn't heard a truck or thunder. Then the rumble started again. This time I was ready for it. I scanned the sky... and saw..... nothing, no lights.... nothing... just heard that creepy sound.
