Geese V-Formation
Topic : IntegrityPerhaps you have heard the geese honking as they fly northward in a V formation. They head toward the grain fields of Canada and Alaska to spend the summer. Two engineers calibrated in a wind tunnel why geese fly in formation. Each goose, flapping its wings, creates an uplift for the goose that follows. The whole flock gains 71% greater flying range than if they journeyed alone. Thats why the leader of the V formation falls back periodically to let another leader take the point, and why the rest stay in line.
