Spalinger S.18
The Spalinger S.18 is a Swiss 1930s performance sailplane. Several variants were built and the S.18 dominated Swiss contests and set records for nearly a decade. Many were active into the 1960s and four remain on the Swiss register. Design and development In the 1930s Jakob Spalinger designed and built a series of wooden, gull wing, gull-winged gliders. His 1936 S.18 had a span and modest performance but good handling. Later variants with longer spans improved performance and the type became the dominant Swiss sailplane. The Spalinger S.18 has a high wing with rectangular plan inner panels. On the S.18 II these extend out to 40% span, with strong dihedral (aeronautics), dihedral over their inner 55% and slight dihedral (aeronautics)#Anhedral and polyhedral, anhedral beyond. The tapered outer panels continue this anhedral out to elliptical tips which have dihedral.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...
