Heavy with chase plane?

At approximately 11:30am EST 3-21-07, I was working on the outdoor landscaping and noticed a quad jet flying overhead, at cruising altitude, so I was unable to correctly identify it. Off to the left side of the jet there was a very small plane seemingly flying “with” it. I immediatley searched flightaware but niether of the flights appeared. My location is KTRI, in northeast Tennessee. This most likely some type of military exercise? Refueling perhaps?

Most likely it was Air Refueling. It’s standard for fighter recievers to fly formation off the tanker while other members of the flight are taking their gas. And the KC-135 (the work horse of the USAF tanker fleet) is a four engine jet. There is an AR anchor and an AR track that cross NE TN.
