Why can bird fanciers not breed ever larger birds, till the birds are big enough to carry people on their backs, or in special baskets? We could then train the birds to carry us to work or overseas for holidays. Simple reins would suffice to guide them, and if we should fall asleep on our way, their innate powers of navigation would return us safely home. A special sling arrangement could be used to catch their droppings, a guaranteed guano bonanza that would more than pay for the creatures' little packets of Trill. Just think, no more noisy, polluting airplanes, and man's dream of flight at last fulfilled. I can't see any downside.
