In these recent accidents with loss of life and injury there are other aspects to consider.
In the mid air, the Beaver was cut apart by the propeller from the Otter. The cabin of the aircraft came down in multiple sections. The poor souls had no chance.
In the Otter, with those injuries were they all wearing their restraints? I doubt it. Granted that plane had pretty high deceleration as it broke free of it's floats, but that deceleration is spread over time which in some ways reduces injury to the passengers.
A week later the Beaver tripped on it's own float. This plane was carrying a load of freight as well as a passenger. How well retained was that freight? Jumping to conclusion I expect that freight came forward into the seating area. We should wait for the truth about that.
And in the most recent with the 185, that was not a high energy deceleration. Granted we do not know what level of agility the soul who passed had, but again, was he properly restrained? One does not need much of an injury along with the disorientation of the tumble to reduce one's chances to get out.
It is very sad to see injury and death but many times there are complexities that cause most of the personal loss beyond just being in a crash.
Sorry if this post was too graphic but there are reasons beyond the simple view why there is more injury or loss of life when something goes wrong.
