I don't agree. Many of the non-fatal accidents are not reported at
all. I know of two accidents here in Arizona that wrecked gliders but
with only minor injuries to the pilots. Stall/spins are usually fatal
as are most accidents involving uncontrolled flight into terrain, but
most outlandings or controlled flight into terrain are survivable,
especially in newer gliders.
