The local Coast Guard base here has a couple of Sikorsky Black Hawk helicopters, and they very often fly training missions that involve long ovals. Many times, one of the long sides of the oval is above my back yard so I hear them.
They are on the Weather Channel's sea rescue shows more than any other bases, as they cover a substantial portion of the Atlantic coast.
