Well I guess you can improvise a lift off with an helicopter, I think it's doable, to just take off vertically and go up. I'm not saying it's entirely safe, but well, it's doable I think, you can eventually improvise that after reading and watching a bunch of stuffs about it on the intarwebs But once you're 50ft above ground what do you do? Same deal... As henry kissinger said about ukraine, I hope you'll be as wise as you're brave...
