A quarter century ago (hard to believe) when I was a young engineer working on the Space Shuttle Mission Simulator at Johnson Space Center, my boss told me an interesting story.

Of course the simulator had been under development for many years prior to the shuttle's first launch. During that development it was noticed that the "motion base" simulator would experience significant vibrations during the roll maneuver that was part of lift off.

It was presumed that the source of the vibration was an elusive software bug. After many months of fruitless debugging NASA finally took the (rare) step of putting a cash bounty out on the squashing of this particular bug.

Nevertheless, no bug was ever found and launch day approached. When the launch finally did take place, and the roll maneuver was executed for the first time, the astronauts were astonished to experience the very same vibration.

For us nerds that was a pretty neat story.

LESSON LEARNED: Pay attention to your simulatons.
