More is less (playing with fire)
It is July 20 1969 in mid afternoon. The place is the lone Lunar Module (LM) at its periaspsis of about 50000 feet above the lunar surface and roughly 250 nautical miles (nm) uprange from the intended landing site upon the Sea Of Tranquility. The LM is travelling at 5560 feet-per-second (fps) with a retrograde attitude. LM Pilot Buzz Aldrin in the right side position, having previously selected Program 63 (P63), and in response to three flashing numbers on the computer's display and keyboard unit (DSKY), presses the PROCEED (PRO) key. As P63 is used for the braking phase of the lunar landing those flashing numbers indicate, respectively : the time of the burn, the time until ignition, and the crossrange distance of the expected landing site from the plane of the LM's orbit. Pressing PRO is to accept that data. The LM's computer is running code called Luminary revision 99. The target of this braking phase is to enter the High Gate, a point 7600 feet in altitude and some 4 nm short of the landing site, at a speed of -140 fps ( ie. descending ) in the vertical direction, with most of the initial velocity downrange gone.
