Soaring Without Rising Currents
Memorandum describing the main problem of soaring flight, which is that it is difficult to maintain altitude and to engage in indefinite continuation of flight without dependence on rising currents from any source. The best chance of success involves utilizing energy stored in the air when the wind speed is constantly and rapidly varying.

The New Interpretation of the Laws of Air Resistance
A closer examination of Newton's formula for air resistance shows that it is well to consider the air as an ordinary fluid, and, indeed for most of the velocities considered, as a non-compressible fluid, so long as the dimensions of the moving body are large in comparison with the mean free path of the particles of air.
