NTSB narrative
A departing Boeing 737-700 passed within 750 feet laterally and 200 feet vertically of a helicopter operating under visual flight rules. Both aircraft were receiving air traffic control services from the airport's air traffic control tower and were operating in Class B airspace. Postincident investigation determined that the controller handling the helicopter did not exercise positive control of the situation by issuing clear and timely control instructions and that the helicopter pilot did not react quickly to instructions issued by the controller.
