Blackhawk Helicopter Over my House-Clockwork

Alright, After thinking on it for a while I decided to post. I live in TN and for the last 3 Tuesdays between 1pm-3pm a VERY fast, very low moving helicopter has flown over my house. I didn't know what kind it was until the guy fixing our a/c told me.

We are right outside Memphis and to my knowledge there are no working Air Force facilities around here. I called our small airport and asked some questions to see if they were aware of anything going on. The manager said he hadn't seen anything but a State Trooper came in last week asking the same questions I was asking.

It was a little unsettling because I had never seen one in person.

Does anyone know anything about this?

Are there any other military bases around? It is my understanding(and given, I am no expert) that Blackhawks are used by the Marines and Navy. I may be wrong, but I dont think the air force uses them.

regardless of where they are coming from, it is always unsettling to see them flying around populated areas.

All the services have one form or another of the blackhawk or as we used to call them in the army "crashhawks..lol
