The NTSB's preliminary report on the Sept. 16 plane crash that killed NASCAR modified legend Ted Christopher states that witnesses did not hear the engine nor see the plane, only hearing something crashing into the Connecticut woods. The plane had enough fuel for the 60-mile flight. Christopher had flown many times with the 81-year-old pilot, Charles Dundas, for more than a decade. Dundas, who also died, was an experienced pilot and flight instructor. The investigation will continue to determine a probable cause.
