strange noises in the night time sky of tulsa.

i live in an area which is known as midtown which is close to the tulsa state fairgrounds, my wife and i have both lived in our house for five years now. we have both heard very unusual, very loud, "jet engines" late in the evening and early in the morning, granted we are close to tulsa international airport, however these are not exactly what i would describe as standard military or even commercial airline sounds. it starts as a low, deeply intense rumble, like an approaching thunderstorm, but then it gets strange, it sounds like someone rollerskating across a wooden floor, it takes the noise and the vibration several minutes to stop, my wife and i have both went outside and looked north, south, east, and west, but the noise is not centrally located to one direction. usually when this occurs there are military jets that show up within a few minutes, there is a air national guard base not far from the tulsa international airport. the military jets go into a holding pattern at about 20,000 feet and do laps around the city as if they were looking for something or chasing something. whatever this object is, it is not a helicopter, a commercial airliner, or even a standard military jet doing night maneuvers, i know there are black op military programs, but i think it is unusual in the sense that these types of crafts are usually not tested in high population density areas, or maybe they are. at any rate, i have never seen the craft, or crafts, but if i do, or can manage to get a recording of the craft or the sound it makes i will do a follow up posting. any info or input would be greatly appreciated.

Regarding the entry: Occurred : 12/22/2004 23:00 (Entered as : 12/22/2004 23:00) Reported: 12/23/2004 9:07:55 PM 21:07 Posted: 1/11/2005 Location: Tulsa, OK Shape: Unknown Duration:3-5 minutes This noise comes from the American Airlines repair facility located at the Tulsa International Airport. As one of the final tests, they back the jets up to a wall and run the turbines at the specified rpm for several minutes. I used to live northwest of the reporters location closer to downtown, and could still hear it.

The neighbor who clued me in to this was an employee of AA. It's amazing how many miles that sound travels when the conditions are right. What you hear are the low frequency waves, kind of like listening to the bass rumbling from the car in the next lane.

Another mystery solved, several more to go.
