Re: Hey Elon
Er, yeah. About that. Elon Musk is pretty much the only rocket operator actively working towards NOT doing that. Every other rocket operator dumps spent stages in the ocean (or whatever remains of said stages after they burn up on re-entry). Also, I don't believe there is any radioactive material present in any rocket at all (with the possible exception of military payloads or interplanetary probes, neither of which regularly land in oceans).
I swore to myself I'd never rise to troll bait. I feel somehow disappointed that I've broken that oath and validated your existence by acknowledging your comment.
