I found this diagram of the Gemini capsule, showing the position of the astronauts: http://img237.imageshack.us/img237/3051/gemini.jpg [Broken] I understand that the astronauts are facing back, since drag will be large. Max g's during Gemini's entry were about 5, and L/D ~ 0.2. However, why are they upside-down? Lift will pull blood to their heads, and I always thought this is a big no-no. Am I missing something here?
