Analysis and Conclusions
It is apparent that there must have been control difficulty of an undetermined nature This may have been the breakage of a structural member or possibly a deformation or bending of a part, precipitating the dive it also seems logical that this had its inception while the fight was in severe turbulence only a few minutes earlier. It is not possible to do more than sumuse as to the genesis of the trouble. because a considerable number of initial malfunctioning could have resulted in the aircraft's turn and final plunge. The physical evidence recorded did not reveal the nature of the trouble. The nature of the aircraft's maneuvers prior to the final dive, and their proximity to the Marion Airport, may suggest an intent to land there; there is no tangible evidence of this
