the idea of having castoring main wheels after a crosswind touchdown is a worse nightmare than anything I've ever dreamt.
I remember reading an article written by an engineer who was in the Tower in the 1950s, observing circuits and crosswind touchdowns on an airliner which had just been fitted with a new experimental castoring wheel system.
I can't remember the aircraft or any of the finer details, except that he said it had been one of the most hilariously entertaining interludes of his life.
