    Thanks for posting this. I didn't know. Been thinking of Bob a lot lately and was thinking of calling Bob last night but got busy and didn't do it.
    Pray for a speedy recovery and God's blessing in every way.

    What a way to advertise the crash worthiness of your aircraft eh'.

    The crash worthiness is what I like about a 4130 steel tube fuselage.

    Why do Italian dogs have flat noses?

    If this had been a wood fuselage what would we be looking at? How bad would it have been?

    Injury? Who knows. Absorbing the hit could be the same. Wood does splinter not yield the same way. The front would have broken off.

    This type of crash is the poster child for why steel tube fuselage construction is still relevant today.

    Yeah, I have considered this a lot after building the Minimax so I'm thinking my next plane will probably be tube. I love wood as thats what I do for a living but that pic above is imprinting things into my mind. Thoughts about aluminum in that situation?

    My uneducated guess is halfway between wood and steel. UN-educated.

    That and why you want a properly mounted shoulder harness.

    That’s why you want a properly mounted 5 or 6 point harness. The crotch strap is the critical link that ties everything together, and in my opinion helps hold the upper deck and lower fuselage together in a crash as well.
    I walked away from a nasty cub crash, in part due to my 6 point harness.

    The best source is Crow Enterprises. This is where we purchased our restraint system.

    Hmm, 'an altercation' with a wire. I'm not one to speculate but looking at the damage, I'm guessing he came in too low, saw the wire too late and pulled the nose up. Tail goes down and the undamaged tail wheel hooks onto the wire. Plane stops dead, swings down and takes it in the chin. Whatever happened in reality, he's a lucky chappie.

    Crow is a source, one of many. While I don’t agree with them being the “best” for me, it is a very subjective term and may be the best for you.

    Something to pass along as experimental builders/owners/pilots, you can install the harness of your choice, without needing a field approval, 337, (or log entry as a minor alteration).
    The race car industry is years ahead of the aviation industry for harness safety, ease of egress, and even comfort. I strongly urge you to look into this area for a 5/6 point harness that works well in your application.
    A rotary release is a key component for me, as they are easy to buckle and with one hand they release everything. Upside down, particularly if under water, fumbling to release your belt while hanging in it is not the best egress.

    I mentioned this before but it’s worth repeating. The old school thought was just a lap belt wasn’t enough, get a shoulder harness. Today, let me tell you that without a crotch strap, a lap belt and a shoulder harness is only so good. (YouTube videos on testing without one)
    In a crash, a lap belt raises (pulled) up under your rib cage and does damage to your internal organs as a result. Not only does the crotch strap hold the lap belt in its proper position across your hips, but it can also vertically tie together the “cage” that is protecting you during the crash process. And when the event comes to and stop, you can release and step out.
    One other note, as experienced from a number of folks in aircraft crashes. It is quite common to use an interia reel for your shoulder harness. They make it extremely comfortable, and in certain models they allow you range of motion to reach items such as floor mounted flap handles, etc. But, it also takes a split second of forward movement for those to “catch” and stop your movement when needed. This split second, along with the incredible flexibility of the human body, has allowed these pilots to still contact the panel, even if just enough to make it hurt awhile. Some military aircraft (choppers) have a lockable interia reel, using a cable and lever (Schroth makes one) but I’ve never seen one in GA. My advice is to not use intertia reels unless needed for that aircraft, and with hard mounted straps “wear” the aircraft as much as comfortably possible. The more you are part of the aircraft the safer you are.

    Just as FYI...
    Thanks to an aviation pioneer/engineer years ago, it was determined that body’s can withstand much higher G-forces than ever expected, if properly restrained. A high speed test track (on rails) was built in the desert and this fellow did nearly all his own testing, far beyond the perception of human limits of the time. Some wild YouTube videos on this.
    Due to the horrendous crashes in the race car world, that industry has FIA and SPI standards that require mfg, test, certification and timelife replacement at a much higher level than aviation. We don’t have a place or need for Hahn neck restraints, but along with the cages that protect them, these drivers regularly walk away to drive the next day, from wrecks that kill on normal roadways. You won’t see any sanctioned race event allowing only a 4 point harness. From baseline Simpson Racing to giant Schroth, or high end custom mfg Safecraft Racing, restraints to save your life, are their life.

    No matter what you use, and no matter who made it, it only works if you use it.

    Question: I've used and abused five point harnesses before, but where does the sixth point go?
