自古以来,人们都有一个梦想,就是能够像鸟儿一样在天空自由自在地飞翔。为了实现这个梦想,人们发明了飞机,只要坐在机舱里就能在万米高空翱翔。但是,还有很多人觉得不过瘾,他们想真的像鸟一样,和扑面而来的汹涌气流有更亲密的接触,并让自己的肢体自由地迎风舒展。 Since ancient times, people have a dream that they can fly freely in the sky like a bird. In order to achieve this dream, people invented the aircraft, as long as sitting in the cabin will be able to fly at a height of 10,000 meters. However, there are many people who think they are not enjoying themselves. They want to really feel like a bird, have more intimate contact with the surging raging airstream, and allow their limbs to freely expand in the wind.
