Back in my high school days, this happened to me during a tournament. Par 4, dog leg to the left. I was going to try and draw my fairway wood around the corner a bit. Made solid contact and my club head broke off at the very tip of the shaft and and flew a good 100 yards into the woods on the left. My ball unfortunately followed suit, but not quite as far. The woods were not that thick so I found both my club head and ball. For reference, my wood was probably 2-3 years old.
