The "Thaddeus Rocket" and the "YOLO Cannon"

During the first two months of last summer, before I turned my attention to entrepreneurial pursuits, I found myself mesmerized with Aerospace Engineering. In fact, I spent up to ten hours each day on my laptop scouring the internet to develop the knowledge necessary to design what I call the "Thaddeus Rocket" and the "YOLO Cannon". The first is a 7 foot tall, behemoth  rocket that was designed to reach altitudes beyond 10,000 feet. The latter is my personalized mimicry of the US military's M72 Light-Armor Weapon Rocket. Of course, both designs are theoretical and will probably never see fruition due to the fact that many of the materials necessary for construction are extremely difficult to obtain without military grade permits. However, I am confident in the viability of both designs. According to my extensive internet research, my plans follow every law of physics necessary to achieve their purpose. Below are my designs:
