Top speed of a P-51 is over 400 mph. Exactly which helmet is going to
help him in a crash?


So... all crashes occur at top speed?


A crash and roll when landing would still be 150 mph or so...in a
cockpit not designed to protect in a crash with roll cages and such. A
helmet helps when you bang your head on preflight, again, a place to
mount the headphones, mic/O2 mask, little else. Also something that is
reflective when you are in the H2O for the helo...place to attach the
strobe. No protection in a crash.
