About this work
Leonard Niemi's Sisu is one of the most successful American competition sailplane ever flown. John Ryan in 1962, Dean Svec in 1965, and A. J. Smith in 1967, all won the United States National Soaring Championships flying a Sisu ('see-soo'). In 1967, Bill Ivans (his Schempp-Hirth Nimbus II in NASM collection) set a national speed record flying a Sisu 1A at El Mirage, California, by skimming across the desert at 135 kph (84 mph) over a 100-kilometer (62-mile) triangular course.
