Most likely it was already cracked from the previous events and he 
miss-interpreted the visual cues.  He would have been wiser to rectify 
it after the first event instead of repeatedly punishing the nose gear 
until complete failure.  But then hind site is always 20x20.

Shimmy on any plane should be correct4ed immediately.  On our fully 
castering nose wheels its even more  important.
