This is the second video I have gotten of this noise, as before…it sounds like a jet hovering around the house for a while then vanishes. It was at just before 1am in Oklahoma City on March 20th 2012. My camera ran out of room before I could finish recording, but I have another video from a different camera that I started recording with that gets it abruptly stopping. I also have a 3rd video from the same evening that recorded the second time this happened early morning on 3/20/12. Don’t know if this is some aircraft they are testing out, or maybe due to solar flares or storms, I just know that I only ever hear this noise late at night and it is random nights, and it is not like any other aircraft noises I hear around my house.
