Not sure if this has been posted before, but really shows how stout a 172 is. For me, it also shows why I like my shoulder harness.

This is the sequel where the same event is on soft dirt. Not so pretty.

I'm curious how fast the plane gets going before it hits the ground. I am surprised at how well the 3 point harness holds, though I still wouldn't recommend them over a 4 point.

NASA Langley does some great work. They are one of our customers at the company I work for. I got to witness their Fokker F28 test, was pretty awesome.

Before the NTSB released the new and (seriously NOT) 'improved' CAROL search tool for the aviation accident db I used a simple keyword search to locate 3 point harness accident injury and fatal outomes. I was surprised at the number of fatals with 3-point where side loads and a loose across the chest restraint where a diagonal vector side load allowed the pilot to slip out of the harness and have a serious head impact on the panel. 4 - point with (especially with inertial retractible) shoulder restaints are way better than 3-point harnesses.

I agree that the 4 point are way better. And I've seem NASA videos where they slip out of the 3 pt easily. But I was surprised in these 2 videos how well they held. I still recommend that my customers remove the 3 pt and go 4, but for those that can't, these 2 videos give me a bit more hope for their survival should anything bad happen.

thank you
