It would probably take less capital/expertise to make a space rocket at this point then a airplane. There is so much red tape that unless you buy an existing airplane company you're probably never going to get sales. US gov has proven it will protect Boeing with massive tariffs if anyone besides Airbus threatens it, means you cannot sell to US companies. So you'd have to start with EU probably, and there is a fair number of established players already.
