Obviously this is early to say this, but based on the discription of the accident and of the injuries, I would say that the airframe did a nice job of protecting its crew and passengers. I cannot help but think about how nice it is NOT to have a big control wheel to go right into your abdomen.
Again, maybe I should wait to post this, as it will end up being premature. But that sounds like a horrific accident and it is nice to hear no lives were lost. It will be informative to hear how the airframe, seatbelts, etc. added to this…
Best wishes for a speedy recovery to them.
