Aerospace Careers for Non-Engineers?

Hello Everyone.
Most of you are professionals in various related industries so I am asking you for your help with some brainstorming.
I am currently 34 years old, have been involved in entrepreneurial things (real estate, marketing, Microsoft Sharepoint systems, food & beverage) since graduating college, but am set on starting a new career path.
I have found through my experience I work much better in a group as a part of a whole than at the top of the ladder and I want to work for a medium to large company. I want to work within the aerospace industry as I love the idea of helping problem solve issues for our next frontier.
I need some ideas from people like you who are in the industry (or similar industries) and to help shed light on other careers available other than going back to school for aerospace engineering. What are some certifications & fields I should look into?
Depending on scheduling availability at my local university or online courses, I am willing to spend the next couple years getting certified or possibly attaining another degree if needed, but I am an adult with adult responsibilities and don't have time to be a full time student so some kind of non-alternative educational degree would be the only option.
My original college degree is in public health and I've never actually used the degree so there wouldn't be much carry over there. My math skills are likely too low for something like engineering, but who knows.
Being completely out of this realm it's hard for me to know and understand the possibilities. I do live in Reno (Sierra Nevada Corporation, Tesla), but am open to moving anywhere. I speak fluent Chinese and also lived in China for 8 years while building a real estate company.

I appreciate your time, energy, and insight.
