2. I was just absolutely adamant about my God-given right to be wishy-washy about where I was going to land. Cdr Neil Armstrong In manned vehicles, the same performance goals come easier in a system not handicapped by idiosyncrasies of the human being… NASA Assoc. Admin. Richard Horner Apollo mission planners and designers sacrificed much to save on weight and fuel, eliminating useful equipment to make the vehicle and its trajectory highly efficient. Historian David Mindell slide 2
