Loss of a rocket pioneer

Wernher K. Dahm, a longtime associate of Wernher von Braun who worked on the V-2 and made important contributions to US ballistic missile programs, has died at 90. Dahm's career included serving as chief of the aerophysics division and later chief aerodynamicist at NASA's Marshall Space Flight Center. He did not fully retire until last year, when he was the last of the von Braun team still working for NASA.
