Part of the 'BOOM'. Fe fusion is the stage where fusion no longer  
releases enough energy to prevent a gravitational collapse of the  
star. Soon all those gigatons of matter are falling back towards the  
core until it goes 'KaBOOM'.

See: <http://en.wikipedia.org/wiki/Supernova>, specifically Type II  
collapse.

Also many cool pictures <http://rst.gsfc.nasa.gov/Sect20/A6.html>
