Exactly. Rocket science is just applied physics. With that grounding and rocketry text would be pretty clear and understandable. At least enough for a manager/owner. It is not like his designing a combustion chamber himself.
A good engineering (and most sciences) degree just gives you the ability to learn more. With my ME degree I am confident if I had that needs that I could grab some rocket science books and learn enough. Heck I probably already know 80% of what would be in them.
Heck, I have a philosophy degree and ended up in nuclear weapons effects work.
