I see this in the opposite way: I firmly believe that soaring is
inherently unforgiving, and it is only through training and judgment
that we mitigate the risks. I think that no conscientious sailplane
developer or human factors specialist would say otherwise.

We fling ourselves through the air in lightweight plastic shells that
have only modest crash protection at speeds up to 150 MPH. We do not
always have full control over the conditions under which we land, or
where we land. Our machines have myriad idiosyncrasies that give rise
to sometimes awkward handling. We often operate these machines in
close proximity to one another, despite the fact that even the
slightest collision can result in structural failure. We often operate
them at altitudes conducive to hypoxia, which causes disorientation.
We fly in contests that place incentive on calibrated risk-taking.

Against all that we have training, skill, judgment, discretion,
engineering, a handful of electronics, some compressed gasses,
statistical probability, and a few books full of rules. And so far,
that stuff has kept the danger down to a dull roar, down to where
soaring is about as dangerous as you make it. It obviously cannot be
exactly as dangerous as you make it; in addition to the subjective
risks there are objective risks such as getting run down by the
occasional airplane that comes from behind. But for the most part
subjective risks reign, and training and experience hold the field.
