When Astor's body was recovered from the water, according to Ross it showed signs of only minor damage to the head, and after it had been prepared for formal identification in Halifax the face was described as discoloured but otherwise showing no signs of damage. Now, you can't be slightly damaged by a falling funnel. Either it misses you or it renders you beyond hope of restoration by even the most skilled of Halifax undertakers. I believe that evidence of minor damage to the head could have been minimised by expert attention in Halifax, but if Astor had been under the funnel when it came down, then all the King's horses and all the King's men couldn't put John Jacob together again.
