"The accumulation of information on the characteristics of controls for high-speed airplanes has been rather rapid within recent months. In the present paper an attempt has been made to piece together some of this recent information in a form that might indicate the types of controls to be used advantageously on swept wings (both rigid and flexible), methods and gadgets for balancing trailing-edge flaps, and the characteristics of some all-movable tails" (p. 1).

"Progress is being made in subjecting to systematic study some of the many important factors affecting the behavior of swept wings at high speeds. In this paper are presented some of the results of recent swept-wing investigations that were undertaken to determine the effects of thickness and thickness distribution, camber and twist, nose-flap deflection, and devices or 'fixes' for improving the wing pitching-moment characteristics at high lift coefficients" (p. 1).

Introduction: "This letter is intended to provide a brief summary of the information presently available on the engineering properties of iron-linonite concrete with the view of adapting such concrete with the view of adapting such concrete for use as biological shielding material in a Hanford pile. By reducing materials and fabrication costs, such a adaptation might effect a savings of at least two million dollars per pile over the present iron-masonite laminated shield structure."
