Unfallbericht:
A Delta Air Lines Convair CV-880 (N8807E) taxied across runway 27L in bad weather (250 feet visibility in fog, indefinite ceiling at 200 feet). At the same time, a North Central DC-9 (N954N) took off from runway 27L. Both aircraft collided.

Probable Cause:

PROBABLE CAUSE: "The failure of the air traffic control system to ensure separation of aircraft during a period of restricted visibility. This failure included the following: (1) the controller omitted a critical word which made his transmission to the flight crew of the Delta CV-880 ambiguous; (2) the controller did not use all the available information to determine the location of the CV-880; and (3) the CV-880 flight crew did not request clarification of the controller's communications"
