The NTSB has released a preliminary report on the plane crash last month in Grundy County. According to the Associated Press, the National Transportation Safety Board’s report says the pilot of the single-engine plane ignored warnings about bad weather. The plane left St. Louis and was covered with ice when it landed in Moberly. The pilot was advised to stay put until the weather improved, but instead continued on. The wreckage was found in a wooded area near Galt the next day. Both the pilot, 82-year-old Philip Joseph LeFevre III and his 47-year-old son Philip Joseph LeFevre IV, died in the crash.
