Abstract : The third Interim Report covers the development program on emergency landing mats from March 15, 1941 to October 1, 1941. The report discusses the service tests of Irving grid in Puerto Rico, experiments with new types of mats, efforts to devise a more readily obtainable open type material, and the development of a new lighter type mat. The Irving grid is a very satisfactory heavy type, that service tests on the steel plank type should be expedited, and large scale tests of lighter types should be undertaken. A transportable runway is not to be considered as an emergency landing surface but rather as a semi-permanent portable runway employed tactically to provide with great rapidity in the theater of operations a hard surface runway for medium and heavy bombardment airplanes. To provide a temporary hard surface runway at an airdrome pending completion of permanent runway. The mat should provide uniform surface and be smooth enough to prevent undue tire wear, have sufficient rigidity to distribute load and prevent development of low spots, and not trap water and mud to cause slippery surface. The emergency or light type mat is definitely a field expedient for the following tactical uses for pursuit and observation airplanes: Temporary runways at advance airdromes; Hard standings and taxi strips at any airdrome; and Temporary surface during repairs to any airdrome. The mat should provide a flexible but uniform surface free from undue tire abrasion, have sufficient bearing capacity to distribute wheel load to prevent rutting, and not trap water and mud to cause slippery conditions.
