Especially for the big family of band - From Ms Neo HJ
This Fall when you see geese heading south for the winter flying along in V-formation, you might be interested in knowing that science has discovered why they fly that way. As each bird flaps its wings, it creates an uplift for the bird immediately following. By flying in formation, the whole flock adds at least 71% greater flying range than if each bird flew on its own. (People who share a common direction and sense of community can get where they are going quicker and easier, because they are traveling on the thrust of one another.)
Whenever a goose falls out of formation, it suddenly feels the drag of resistance of trying to fly alone and quickly gets back into formation to take advantage of the lifting power of the bird in front. (We should stay in formation with those who are going the same direction.) When the lead goose gets tired, he rotates back in the wind and another goose flies point. (It pays to take turns doing hard jobs - with people or with geese.) The geese honk from behind to encourage those up front to keep up their speed.
