The flying chance

Over many generations, humans wanted to fly. Then, only a century ago, humans were able to build a flying machine that could fly by itself. Of course there were many flying machine attempts but they were not self-sustaining and needed and external help such as hot air to lift the machine. or a wind that could carry the machine to certain direction. But I sometimes wish humans develop wings on their back to fly freely around. It will be hard but I think it is worth it. If they couldn't develop a pair of wings by ourselves, then the help of biology will help us get them. So Jerry! Give me a pair of Wings when you become a Biology major!
