well, if you're familiar with KBTL (Battle Creek, MI), its the home of Western Michigan University's flight school. One day during the start of my commercial training the pattern was extremely full. Two aircraft on right traffic for 23 and two in left traffic (I was in left traffic). The tower controller was new but was handling the busy traffic fairly well. Then it got a little busier, two more aircraft came inbound from the east gate and there was one on approach (ILS 23) with a few aircraft in line waiting to depart. The controller was trying to get the aircraft waiting, out and started to get mixed up with all the Western call signs. Finally, it reached the point were the controller got so confused that all of us in the pattern were told to sequence ourselves. Somehow it worked out but needless to say, my instructor and I decided to land instead of doing another touch and go.
