I find this interesting, >Simply stay in the waiting orbit until the target reaches the angle 3 from the local vertical [...] On terrestrial flight (airplanes) the standard approach to landing glidepath is 3°, while the standard rate turn is 3°/sec (a "two minute turn") — I wonder if 3 degrees is some magic value in flight dynamics, perhaps determined by our local (Eatths's) gravitational force (G). /Acey Disclaimer: I haven't read Buzz's thesis, so this is purely an off the cuff observation.
