Off-road Mobility Research: 2nd Semi-annual Technical Report, 9 February 1967 - 8 August 1967. Under Contract DAHC04 67 C 0005 with U. S. Army Research Office-Durham, Durham, N. C.

This technical report was produced by the Cornell Aeronautical Laboratory in 1967 as part of a series of research projects commissioned by the U.S. Army Research Office. The document was generated under contract DAHC04 67 C 0005, reflecting the era's intensive scientific focus on vehicle dynamics and terrain navigation. At the time, such research was vital for improving the performance and reliability of military transport across diverse, unpaved landscapes, necessitating rigorous mathematical modeling and experimental testing.

The design of the report follows the standardized formatting common to government-contracted technical literature of the mid-20th century. It served primarily as a formal vehicle for disseminating data to military planners and engineers rather than a public-facing document. The Cornell Aeronautical Laboratory, which later became Calspan, was a key contributor to these high-level research initiatives, and this specific volume acts as a window into the evolution of off-road mobility theory during the late 1960s.
