% Apollo lunar module landing guidance
If no inputs or outputs are specified it will simulate a lunar landing
using the guidance system. Three phases are implemented:
P63 Braking phase
P64 Approach phase
P66 Terminal descent phase
The land flag is used in P66 to tell it to land.
x is normal to the lunar surface and z is downrange
