Narrative:

After departing mir on a scheduled flight, we were descending into eyw out of 2800' approximately for 1500 under navy key west approach. Both myself and my first officer saw the small aircraft at the same time. There was and would have been no time for reaction. I only want to point out to you and your readers that even though you're in radar contact, keep looking and watching, and if you don't have a transponder, get one, if you have one, use it. The small aircraft was never seen on radar until about 5 minutes later after we had landed, and called the controller on the phone, the controller said that she had a weak target at 2000'.
