No one has mentioned anything about detonation of the engine as a factor in crank failure. Detonation causes undue stresses on a crank by creating a hammer like force generated from the piston through the rods to the crank. This hammer-like shock wave being imposed on the crank causes severe overloading. Detonation can destroy an engine very quickly. How many of the crank failure engines actually were subjected to detonation. The only one who has confessed to having detonation was Mark Langford and his was a brief period on departure per his post of June 10th. Just something else to think about.
