The question was “what happened to that?”, and the answer is “it’s very actively happening”. Whether they actually succeed is a whole different question that I can’t answer, but I wouldn’t bet on it.

It sure is questionable, but so far each test got further than the last one, so while I wouldn’t be making any bets on it working, I’m not going to discount it either. People said the same thing about reusable rockets and now it’s no big deal. They might have a chance, as long as the president of SpaceX manages to keep Musk away from it.

See? I’m sure we can make up a list of women we can also send on the submarine down to the Titanic rocket to Mars.

I sincerely hope this is sarcasm. Either that, or you are completely unaware of how the American justice system favors the wealthy.
