The flight of the birds has inspired one of the oldest dreams of Mankind. It has frequently been copied, but never fully equalled. The flight of the insects also constitutes an area of studies and researches for aeronautics. From dragonflies to the big soaring birds, many are the species that have been mastering the science of flying for a very long time. As nature is a source of inspiration for men, we have to ensure that it stays so for the generations to come.
