The last post got me thinking and I think i?ll try it : use a cep type headset (I have a Lightspeed Mach-1 I?m not using) inside of a ANR helmet (or ANR headset) to see if it has even more noise reduction.

The flight helmet sold on Aircraft Spruce is just remanufactured motorcycle half helmet with the headsets screwed on the outside of the external shell. The Icaro design looks better though.

Gibson and Barnes. Outstanding equipment. Quick turn-around for my USAF helmet's modification for GA, and again to install their noise cancelling earpiece system. Outstanding quality and workmanship.

I have my son's F-16 helmet with visor, O2 mask, and have a two plug battery operated com cable. On the microphone side the com interface cable needs a new plug. I used to wear the helmet when I owned a Yak. The helmet has been in storage for about 10 years. Gibson did the mod.

Asking $400 including shipping.

I am presently in San Diego, if you would like to drive down to take a look let me know.

Regards,

I have always been under the impression that wearing a good flight helmet would go a long ways in saving your butt if you had a high G impact and crash.

But, there is evidence that a helmet really won't do that much for you. Two recent crashes, a T-51 and a P-51, illustrate the point.

Both crashes were fatal. In one case, the pilot was wearing a helmet. It did not save him.

In the P-51, the passenger died from the impact. He was not wearing a helmet, but the UK authorities stated in the accident report that a helmet would not have saved him.

So...what real good is a helmet? Unless your are a biker, then it makes a lot of sense.

Bird strikes do not concern me that much, as the bird must first fly through a 90" propeller. Won't be anything left after that, but blood, guts, and feathers.

Look up some bird strike accidents and you'll learn how wrong you are. Intact, live, very active birds have ended up in the cockpit after coming through the windshields of RV's (and Cessnas, Pipers, etc. etc.). They will be injured by passing through the plane of the propeller, but they are definitely not going to be just turned into mush that can't hurt you.

Setting aside bird strikes, and in over 25,000 hours of flight time I have never had a windscreen impact, are there any accident reports that clearly state the pilot's life was saved by wearing a flight helmet?

I know of multiple accidents (mostly P-51's) where the helmet was of no help.

This is a great discussion area, I'm glad you brought it up.
Aren't you omitting key information from your assessment? Consider that a helmet is designed to protect specifically against impact forces directed to the skull and face. What were the actual forces those two people suffered? Whole body impact? Central torso blunt force trauma? Excessive impact forces in (or out of) line with the spine? Internal organ injury from high-G trauma?

Of course the helmet wouldn't have prevented those deaths. High G impact effects the entire body, not just the brain. I urge you not to let the all-or-nothing generalization lead you away from understanding the helmet's basic purpose. Clearly those forces were way outside the helmet's designed sphere of capability. I got hit by a typical WHAMMO north Texas summer updraft while wearing my helmet for formation work, and I hit the canopy so hard with my helmeted head I thought I had cracked the plexi. I have a friend who ground-looped his taildragger no thanks to an unexpected crosswind, totaling his airplane and smacking his head on the glareshield: His lowered visor protected his face. In my F-4 Phantom days, a WSO buddy lost his rear canopy during a tactical low level flight: It cracked his helmet on the way out at 480 KTAS, but he survived it with a minor headache and a new reputation as an iron-skulled badass. Any of these could have ended up differently without our helmets.

As for the bird going through the prop, all that 'blood, guts, and feathers' still retain nearly all of their original mass, moving at the speed of our forward velocity:

I wear my helmet during formation flying specifically because I an NOT clearing for birds (and north Texas turkey buzzards are so large they ought to be ADS-B participants).

A helmet is just a tool, with specific purposes. It is not a panacea, but it is still a very useful safety tool.
