Paper Tiger, Yes, the 767 was directly over the field at around 4000' when the controller stated the gear was down. I wish I was able to hear the response. Another strange thing is that all departures were on North headings (32L,R, 4L), so the A/C had either turned South after TO and then circled back North at that level, or was making an approach to MKE from another airport altogether. It was interesting.
