It would be like believing in Santa Claus, because in order for a "hollywood" production simulation to be incorporated into the mass of monitors and controls at Houston Mission control, Santa and an army of technicians, IT personnel and graphical experts would have to drop down the chimney while the controllers were asleep, leave their bag of goodies in the systems, and get out before the 50 or so controllers woke up.

They would probably have to repeat this trick dozens of times, as anyone who was involved in systems integration in the 60's and 70's knows that such a complex system would never go without a hitch - not even the tenth installment.

Then the simulation would have to work without a hitch for several years, when just the slightest deviation from reality would be picked up by the controllers.

and why do i continue to smoke weed to the point that i think about crap like this so much that i even forget about doing other things, like being productive, or even simply moving?
