In the fighter aircraft environment it's an unquestioned necessity and
we learned to live with it and were glad to have the helmet.

A lot of things can happen in a bailout, from the reason for the bailout
through egress from the aircraft to the landing and including the
circumstances you find yourself in once on the ground. You can get hurt
in any or all of those phases, and a helmet is important protection for
your sensory and decision-making apparatus. The same goes for abnormal
landing situations, of course.

Though my DG-303 has enough room under the canopy that I might be able
to wear a small light helmet, it would undoubtedly restrict my ability
to move my head around in the cockpit and therefor limit my ability to
see to the sides, down, up, and aft--especially up and aft, a place I
want to be able to see in a thermal with other gliders. It would also
mar the inner surface of the canopy, and contribute reflections in the
plexiglas. A soft dark helmet covering to solve those problems may
contribute to heat build-up, but there would be plenty anyway. The
bucket hat does not pose similar restrictions, as it can be bent out of
the way or taken off with a sweep of the free hand. It can also be
dampened for cooling.

The seating position in my glider and the space in the cockpit are
vastly different from what I had to work with in USAF jets. I will
retain my ability to clear the airspace in preference to wearing a
helmet in my glider, and in preference to adding more weight to my
64-year old semi-reclined neck during those long hours of soaring.

I would seriously consider wearing a helmet in the tow plane, however.

I 2nd that part about the tow plane - we had a tow pilot seriously
injured when he landed short due to an engine malfunction. To make
matters worse, the plane only had a lap belt (a shoulder belt was
installed afterward). The plane was a Citabria, which has lots of
exposed steel tubing and sharp pointy things. I read of a pilot killed
in an otherwise survivable accident when his head hit a long bolt in
the cockpit (it had been replaced for some reason and they didn't have
the proper length bolt on hand).

Visibility and fatigue are over-riding factors for use of helmets in
gliders, however. A Ruger hook on front hinged canopis is definitely
something to consider (this captures the rear of the canopy during
ejection, preventing incapacitation).

Of course, glider design has definitely improved thru the years. So
buying a newer one isn't a bad idea either (I am begining to sense an
indisputable argument for trading in the old gal - glider that is).
