ABSTRACT
Nature has played a significant role in creating a desire in human beings to develop flying machines. It is well known that bird (of course with flapping wings) flying had a strong influence in the development of gliders and aircraft. Even in plants, the concept of flying over reasonably long distance to spread the seeds exists. For the sake of illustrating the beauty of nature, a few examples of flying fixed wing (Figure 1.1) and rotating wing (Figures 1.2-1.5) seeds are shown. The rotating wing seeds can be further divided into single or multiple wing seeds.
