Dead birds are flying again -- this time, as drones
Hassanalian then settled on two types of motors to be placed inside the birds. One generates a flapping motion; the other helps the bird glide with straight wings. Hassanalian said he has discovered that many birds are adept at flapping, but birds with wings lower on their bodies, such as albatrosses, flap less frequently and are best for gliding. By studying both, scientists hope to enhance aviation technology regardless of their flight mechanisms.
