What you may be missing is recognition of the fact that the helmet in
modern, high-performance aircraft functions primarily as an anchor
mechanism for electronics and an oxygen mask. It does shield the
noggin from the canopy bangs that potentially result from abrupt
maneuvers, but it doesn't add all that much to "crash worthiness."

In fact, most states will not accept a military flight helmet as a
substitute for a certified auto/motorcycle helmet.


Here's a quote of the flightsuits.com website in reference to one of the
helmets:

Caution: HGU-55 helmets have been designed for use in fixed-wing
aircraft and offer limited impact protection. Users with different
applications should consider helmets with greater impact protection
designed specifically for their applications.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.
