In 1971 Communist government of Soviet Russia has order a development of the smallest passenger helicopter in the world that could carry one person and can be folded in the tube that can be carried also by one person. They had plans to use it on the benefit of Soviet Army and Russian intelligent service.

Here we can see what they got as a result of this order. It was a Ka-56 “Wasp” helicopter, fully functional and could be used and between uses carried by one man.

我操!先进的战术武器!单人空降可以飞行100公里以下!
不错!

这个东西不慎重使用很容易出危险啊

俄国的人创新能力，技术革新的能力，值得赞同。
