The problem becomes a paradox when you consider birds. Bird bones are much smaller and less dense than ours. Then you must consider that a bird can already fly, which means that the airplane is not a necessity for them. In my humble opinion, in light of the prior facts, I do not subscribe to the belief that bone attributes are a reliable means of determining airplane fare. Or rather, I propose the use of volume, instead.
