Could humans fly if we had wings : Understanding the science behind how birds fly and can humans do it too??

I think every person on this planet would have been fascinated by seeing birds fly and would've dreamt of being able to fly high in the air, at least in their childhood. Today we are going to look at all this topic and we shall find if we could ever give wings to our dreams. For understanding this we need to look at how birds and insects fly.

How do birds fly with wings?

Birds are capable of flying because of the evolutionary capabilities that they have attained. Birds have their fore-arms developed into wings that help them to fly. Besides that their bodies are light in weight because they have hollow bones i.e. their bone density is relatively low that makes them lightweight. Their bodies are spindle-shaped which help them fly against air resistance and glide effortlessly with the air current.

Some birds have wings which are relatively big and they fly by flapping and gliding with the air current while small birds like the Hummingbird have small wings, and thus they fly by constantly flapping their wings to keep themselves in air. Even insects fly by flapping their wings constantly with high intensity.

Could Humans fly with wings?

We've all seen pictures of angels with wings which always seems interesting but if try and make it real but building a pair of artificial wings that help us fly.

Now we've decided to make a pair of wings for ourselves lets take the possibilities that we have in designing them. We could either make small wings and flap them constantly with high intensity or we could simply make some bigger pair of wings that we could flap with less intensity.

If we design a pair of small wings taking the example of a hummingbird we won't be able to fly, because our hands cannot produce enough energy to flap the small wings with such high intensity constantly. Let's say we took the other alternative of building huge wings to support our bodyweight it could be as long as 6-7 meters. But still, this doesn't solve our problem because our muscles aren't enough strong to be able to flap such huge wings.

So it is impossible for us to fly with artificial wings using muscle strength unless we were at least twice as strong with half of our body weight.

Could Humans fly with artificial wings?

If we look at human anatomy we could only have muscle mass up to 40% of our body weight so we cannot use our strength to fly.

 But what if we're not as muscular we're much smarter then them so we could design something that is powerful enough to make our artificial wings flap while being significantly weightless. 

We've looked at all the facts, and it seems almost impossible for humans to fly on their own but everything that we have achieved so far seemed impossible when it was discussed among people.
