If you  
have a minute or  three, take a look at some of the pictures of the  piston 
damage and see if you  can explain what happened? (This is the  "Ask" part) 
Another picture shows  how the aluminum was blown into  the inside of the 
piston, metal spraying. Cool  to see, unless it is  your own piston, I 
guess. So - 
What  happened?
