I figured this would be a useful resource for anyone who didn't want to shell out the 180$ to hear it from an instructor(not that that's all MSF does, but it's a good deal of it).

Both the shell and the liner compress if hit hard, spreading the forces
of impact throughout the helmet material. The more impact-energy
deflected or absorbed, the less there is of it to reach your head and
do damage. Some helmet shells delaminate on impact. Others may
crack and break if forced to take a severe hit; this is one way a helmet
acts to absorb shock. It is doing its intended job. Impact damage
from a crash to the non-resilient liner may be invisible to the eye; it
may look great, but it probably has little protective value left and
should be replaced.
nice...some good readings

i was reading about helmets and how some are designed to crack. i once got flamed for saying that on here before.
