Analysis

A Piper PA-31, N35206, (south central air flt 59) was cleared to taxi to rwy 6L. The wx at that time was foggy with about 1/8 mi vsiibility, but the RVR was improving & the arpt was expected soon to be acceptable for takeoffs. The PA-31 crew taxied & waited in the holding area for the visibility to improve. A Douglas DC-10, H7339, korean air lines flt 084, was cleared to rwy 32; however, while taxiing in the fog, the DC-10 crew inadvertently taxied to rwy 6L/24R. Tower psnl were unable to see the acft in the fog & were unaware of the DC-10'S position. The DC-10 was cleared to take-off on rwy 32 & the PA-31 was cleared to hold on rwy 6L. The DC-10 crew taxied on rwy 24R & began taking off toward the PA-31 with 2400 ft of rwy remaining. Its estimated takeoff distance was 8150 ft. subsequently, the DC-10 collided with the PA-31, continued off the rwy & hit stanchion lights, small trees & rough terrain. An investigation revealed the DC-10 plt did not confirm his position by using his compass & that there was a lack of legible twy & rwy signs.
