A goose has problems carrying its own Weight into the air.
Assume it weighs about 5kg. To also carry a human of mass 90 kg it would need to have a wingspan at least 16 times bigger. But the bigger wing span would make the goose much heavier - more bones, feathers and muscles to move the wings say 10 times heavier.
So our new 50 kg goose could only carry someone weighing 35 kg
The wingspan would have to be even bigger say 50 times. That means we are heading towards a 60m wingspan. When that wing was beating the wing tips would be exceeding the speed of sound and would need to be much stronger and therefore much heavier.
Here we go again!!!!!!
