Correct - found this reference at http://www.german-way.com/famous-wernher-von-braun.html

In 1931, von Braun began learning to fly gliders, taking private lessons in Grunau, Silesia. He later became a skilled pilot, eventually flying everything from fighters to helicopters, but his goal of one day flying in space eluded him.

Would be interesting to know if von Braun did fly gliders in the US.
