Excerpt from Aerial Navigation

The ascent and descent of balloons could, therefore, be more or less completely regulated; there was thus far, however, no suggestion of controlling the direction. The question of the buoyancy of the balloon necessary for the ascent still commanded exclusive attention, with the immediate result of giving a wrong direction to observations and to scientific investigations. This led to constant disappointment, and, strictly speak ing, no further progress in the scientific develop ment of aerial navigation was made for nearly a century.
