You are talking to one of the least tech savy people on the planet. I don’t have a clue. However, let’s hope their need for symbolism will be their downfall.
I’ll try to explain. I typed in Owl structure and this picture of an owl wing popped up It was only the bone structure. I thought ok. So I clicked on the owl wing and information on the barn owl came up. I went back and again clicked on the picture of the bone structure and this site telling about an owl like structure has been developed to fly over most any type of land. There is an algorithm developed to take measurements of all terrain by using this owl like structure. Owl are known to fly quietly and be very mobile. According to the article.
