发帖数: 147 | 2 hang glider的安全如何？
毕竟降落，全靠双腿落地，缓冲，当然hang glider比以前在国内玩过的滑翔伞还是安
全很多的，滑翔伞在无上升气流作用下，真的会自由落体的下降！ |

发帖数: 147 | 3 滑翔伞一般都是没有动力的，有动力看别人玩过，但是觉得比较复杂了，发动机在背后
，背着的。听说过朋友的一个朋友，玩滑翔伞多年了>5年，结果还是去年在一起事故中
，丧生了，就是上升气流在山区忽然消失.....
hang glider 就是没有气流作用，至少还可以通过滑行，保持速度和升力，有动力的
hang glider，直接打开发动机就可以了。 |

one thing to mention is that Wright brothers were also running their bicycle

they started with glider, tuned for aerodynamics and got powerful gas engine

it is this enterpreneurship in people like Edison,Wright brothers,

Samuel Cody invented a kite known as the Bat, that he proposed be used for

the War Office for them to allow him to conduct trials between 1904 and
