Now enlarge this bird and put seats for passengers into the bird’s belly and you got an airplane everyone wants to fly ( the current one I would like to fly is the A380). Best thing about this this bird – no dropping bird shit. Just imagine the size of that bird poop in the enlarged version for long distance travel. Run, Splash and Yikes. But in order to poop the bird has to eat. What would a bird Robot bird eat?
