Fact Checker: Charlie Garcia

The research for this video took about 4 weeks with the help of the reports, books, research papers, and nasa communications below. Charlie Garcia also kindly lent his expertise in rocket propulsion as a fact checker and advisor for the project. We normally show numbers on screen, but numbers got mixed up during the convoluted writing process and it’s now 12 pm the night before upload and I just can’t bring myself to link them all appropriately, but rest assured that all information in the video comes from one of the fantastic resources linked below.
