When I saw the first part of this video, I was thinking its just a remote control helicopter. But once the pilot took his seat below it, I began to understand the potential here.
Yes, it’s very noisy. And yes, it looks incredibly dangerous. But using something like this to “jump” to the top of a tall building or an emergency rescue craft for remote accident sites. Well, it has more than a little potential.
