 More food for thought........
 I recall that it was Martin Hollman who showed a video of the actual
 failure test of the Lancair IV wing.  This was cirra 1993 at an EAA meeting
 at  San Carlos, CA.
  If memory serves,  failure was at barely 9 G's.
 IMHO, be damn careful with the numbers.  Regards, Bill Hogarty
