The National Transportation Safety Board says the cause of the crash that killed Senator Paul Wellstone and 7 others was a result of pilot error. The crash happened in October of last year during the heat of Wellstone's campaign for a 3rd term. The NTSB said the plane lost air speed, and the aerodynamic lift required to keep the plane in the air, as it approached the airport in Eveleth. The Board also agreed with investigator's findings that the pilots lacked proper training in crew coordination. Former Wellstone campaign director Jeff Blodgett says the findings of the report are difficult to take.
