I more than had my hands full one night with two 737s inbound to EDDH. They ended up in, then East Germany, both at FL 290, and in formation. Neither felt in a position to do anything else and I was being kept busy by Air Defense screaming in one ear and the Supervisor screaming in the other. Both were telling me to do something, but neither had any ideas what. Eventually wegot somebody in E. Germany on the landline and he just said, "What aircraft. I am not looking at the radar. "
