At the time of the incident low visibility and a low cloudbase (7/8 overcast at 100 feet and a general visibility of 1700m in mist) made visual control from the tower impossible. Low visibility procedures were in force. Delta flight 39 had been cleared for take-off from runway 24. Almost at the same time a KLM Boeing 747, being towed and accompanied by a yellow van was cleared to cross runway 24 at the position of exit 2. During the take-off roll the pilots of DAL 39 observed the towed Boeing 747 crossing the runway. The take off was aborted and the aircraft brought to a standstill before reaching the position of the tow.
The following causal factors were identified:
(i) Low visibility weather conditions which prevented Air Traffic Control to visually identify vehicles on the ground;
(ii) Inadequate information during the radio communications between tow (yellow van) and Tower;
(iii) Misinterpretation of position and movement of the tow;
(iv) Take-off clearance without positive confirmation that the runway was unobstructed;
(v) Insufficient teamwork and supervision.
