Cause of injury in accidents
I've been trawling the usual statistics (AAIB, NTSB, CAA...) whilst putting together some course notes, looking in particularly at aircraft crashworthiness.
There is lots of very clear analysis available concerning the causes of accidents, and the classes of aeroplanes that suffer them.
However, what I can't find is much evidence as to the actual causes of injuries (fatal or otherwise) when they occur - for example impact injuries, smoke, fire, emergency egress, drowning, etc.
Does anybody know of any such analysis that they can point me at?

Genghis,
Several come to mind. University of Southern California Aviation Safety School and NASA.
From personal experience, the lack of or lack of wearing a shoulder harness / inertia reel in a forward impact guarantees a head impact with the yoke or panel. Aircraft with a control / cyclic stick will impart blunt trauma or impalement to the chest / abdomin. I know of a BO105 pilot who ( for whatever strange reason ) was only wearing his lap belt and ruptured his aorta on the cyclic stick in what otherwise was a very surviveable hard landing.
Saw some NASA ( I think it was NASA ) film 20+ years ago using " swing towers " to control the angle and velocity of airframe impacts with ground and objects. One interesting finding was that some long, thin frames
( 20 - 40 Paxs ) would momentarily fold up and then reextend to almost normal shape in low angle flat terrain impact. This could only be seem in slow motion. Explained a lot of previous crush and spine injuries in these types of frames that had been a mystery in the post crash investigations
as the airframe had flexed and reextended to almost normal shape.
Let us know what you find, of much interest to me.
Best regards,
C

Wow!! Aerolearner,
interesting sites, Pprune is going to worsen my myopia
, perhaps when presbyopia occurs (vision changes due to age), however , I'll become more emmetropic ('perfect vision') therefore I conclude Pprune is saving my eyes for the future

The database was initially intended to carry out analytical work aimed at improving occupant survivability. More recently the scope has been expanded and it now includes information on non-survivable accidents.
