What I was getting at is that most of the power sets TRY to make sense, in universe. Super strong Metal man? Fine. Flight? How is my question. Essentially, you're making a marvel universe Man of Steel Superman.

If you have control over your metal bits and can shape change, like a liquid metal person, then I would start thinking flight can be figured out. I would be concerned with you freezing over though, or melting like the T-1000 Terminator. (The liquid one)

Also, why such a specific speed?
