• "Mathematical models, simulations, and early Gemini flight experiences determined that the optimal altitude difference between the two spacecraft was fifteen miles, and that the ideal transfer angle—the angular distance the Gemini spacecraft needed to traverse during its rise to the higher orbit of the Agena—was 130 degrees rather than the 180 degrees or halfway around the globe called for by the so-called Hohmann transfer."
• "He provided himself with a cross-staff for determining the angular distance between stars or other objects, and, finding the divisions of the scale inaccurate, constructed a table of corrections, an improvement that seems to have been a decided innovation, the previous practice having been to use the best available instrument and ignore its errors."
