Triangle over Keota, OK

The report, as filed

Hello, I was walking out to our shop at 10:30pm CST because I saw the lights had been left on in the back of the building. While walking back to the building, I heard a low rumble and expected to see an aircraft overhead. I saw a large triangle shaped vehicle directly overhead. At first I thought it was at about 2000 ft agl, but I noticed the rumble noise was trailing the vehicle so I think it must have been higher. This object was against a clear moon lit sky and was black and easily defined in shape. It had bright white lights at each of the three corners with a pulsing red/white light in the center. I am a commercial pilot and can identify aircraft easily. This aircraft did not have the standard red/green indicator light. I was heading on a straight northerly heading and as it past I saw what appeared to be a extension, like a drogue line with a pulsing red/white light, so I was thinking it might be a military aircraft refueler. But as it continued on its heading, I watch as the extended object began to rotate around and above the object and it remained in that position until over the horizon.
