In separate interviews with the NTSB after the incident, Capt. Timothy B. Cheney and First Officer Richard I. Cole told investigators they were in a "concentrated period of discussion" over a new monthly crew flight scheduling system in place as a result of the merger of Delta and Northwest. Both accessed and used his personal laptop computer while they discussed the airline crew flight scheduling procedure. Cole, who was more familiar with the procedure, was providing instruction to Cheney, the NTSB said.
Flight 188 had 144 passengers, two pilots and three flight attendants on board. It landed safely about an hour after its originally scheduled time. Both pilots have since had their flying licenses revoked.
