The NTSB has released its final report on the October 25, 2002, accident in which U.S. Senator Paul Wellstone of Minnesota and seven others were killed at Eveleth, Minn. The twin-engine turboprop King Air A100 didn’t have a cockpit voice recorder, so there was no possibility of investigators learning what the pilot and copilot might have said to each other about the way things were progressing during the VOR approach to Eveleth. Investigators had to rely on other things to figure out what caused the airplane to experience an aerodynamic stall at a critically low altitude. In reconstructing the accident scenario, investigators used radar data, ATC audiotapes, aircraft performance numbers, interviews and a large body of experience derived from investigating other accidents.
