The eagle is reputed to fly at altitudes of up to 16,000 feet. This ability is dependent on a process of renewal of feathers, beak, and talons. This process is not painless and is necessary for the survival and longevity of the bird. It seems airlines take after eagles, periodically requiring an infusion of youthfulness to not only fly but also to live up to a ripe old age.
