Could an iron twinborn “fly” by drastically increasing his weight, pulling hard on a counterweight so it flew above him, then decreasing his weight drastically and pulling himself up by the counterweight, and repeating?
It’s plausible. It’s kind of a ‘Thor-like’ way to fly, isn’t it? (For those unaware, he throws his hammer and it carries him with it, and STOP THINKING.) I played with this idea, but the trick is not getting hit by the counterweight as you pull it to yourself. If you could stop that, you might be able to manage it, but it felt pretty hard to pull off to me.
