I often have a creative thought, and I have always wanted to create something like a jetpack, or something of that nature, maybe it stems from something I seen a movie or two, but I always thought it could be possible. Now as I look around and see that someone has created one, now that brings about a certain feeling that what I want to achieve can be done and it just takes time to see it through. I wouldn't know how many parts are actually needed, but I would start off with the actual outer casing as a beginning, then from there start designing parts and pieces to put them together as well as scale them accordingly. In order for me to get the correct dimensions I am sure I would have to make a model of it somehow and see what all it may take to complete the full design. I want to actually brainstorm on this due to the fact that I actually thought of this years ago, and I want to see if I can at least draw up a real blueprint, I will get back to you all with this, hopefully in the future.
