    Leonardo's annotations suggest that a linen aerial screw, if turned quickly enough, would push against the air and lift the structure into the air. The notes indicate that Leonardo built small flying models of the aerial screw, but there were no indications for any provision to stop the reaction against the rotation of the sail from making the ...

    Each photo covered two hundred and twenty-five square miles. One of its first government contracts was an aerial survey of New Mexico to study soil erosion. [20] A year later, Fairchild introduced a better high altitude camera with nine-lens in one unit that could take a photo of 600 square miles with each exposure from 30,000 feet. [21]

    If the plane is flying from South to North, shadows will not be clearly observed. [2] For photo interpretation, it is preferred that the image is taken so that the shadows can be clearly observed [2] as shadows can highlight the relief of the topography. [2] This orientation of the image also helps geologists link the 3D pictures to what they ...

    It has been claimed [59] that these sketches show that Cayley modeled the principles of a lift-generating inclined plane as early as 1792 or 1793. In 1796, Cayley made a model helicopter of the form commonly known as a Chinese flying top , unaware of Launoy and Bienvenu's model of similar design.
