You can't report vague descriptions! Haven't we learned anything!
Around 126th and 69 there is a person who owns a black UH-1N twin Huey. He has been flying it quite allot, all hours of the day and night. This may be what you have been seeing. There are also alot of Black Hawks that fly over that area from the Shelbyville National Guard air station going north to Grissom or Ft Wayne.I have also seen in the same area and around 70 and 465 on the east sice (landing at the State police post) a unmarked CH-47F Chinook
