Could well be right John, and more than plausible. The old saying “There's more than one way to skin a cat” could be altered to “There's more than one way to cause an accident.” That though is prompted by a guy telling the story of trouble while landing a Beech 18. Shortly after touchdown one of his legs locked up and the aircraft started pointing to that side of the runway, managed to maintain control by his useful leg using the brake to get the nose back. His point was if the very worse had happened and he not survived, investigators would have put it down to loss of control, but been scratching their heads how a highly experienced pilot in type lost control in benign circumstances.
