safer than power flying?

The following, from _Sails in the Sky_, caught my attention:



"Is sailplaning safer than power flying?" someone asked.

"We think so," said Jones. "You're not moving as fast, there is no
danger of an engine conking out, no chance of fire. And when you soar,
you have to keep your mind on what you're doing. In power flying some
pilots count on the throttle to get them home, and they get into
trouble. In soaring you know you have to keep mentally sharp to work
yourself back to the airport."



True? False?
