A joint venture called Aviation Partners Boeing successfully integrated winglets into the Next-Generation 737–800 by retaining performance improvements with minimal weight penalty on the existing 737 wing design. Program challenges included developing both retrofit and production configurations using a common winglet design, causing minimal impact on all customers, and causing minimal disruption to the 737 production process. Winglet benefits along with improved performance include reduced engine wear and enhanced visual appeal.

A new low Reynolds number, natural laminar flow airfoil design and its impact on performance of a generic light sailplane are presented. Several previously published airfoils, the Liebeck/Camacho LA203A and the Somers/Maughmer SM701, were used as a starting point. They are examined along with several new attempts to further the state of the art for natural laminar flow, single element airfoils. The computational tool XFOIL was used to analyze these airfoils, and the resulting data were adjusted and applied to a generic Sporting Class sailplane design. The results indicated that overall performance improvements are possible over the SM701, the LA203A, and a third reference airfoil.

The original paper published mistakenly did not include Paul Dees, Boeing in the author listing.

World War 1 began with the airplane as a frail, unarmed means of observing enemy troop movements and ended with the airplane as a powerful, much more evolved weapon of war. There were specialized roles for fighter, bomber and ground attack aircraft as well as newly developed aerial strategies and tactics for operational effectiveness. Many aircraft design technologies greatly matured during the war. Four will be the subject of this paper: Drag reduction, aircraft handling qualities, stability and control, airfoil design technology, and structures design technology. Propulsion and armament also matured greatly but are not discussed in the paper. The discussion of drag reduction will illustrate the innovations of the British on external wire bracing drag, the French on cowl design and the Germans on cantilevered wings and induced drag.
