If he disappears again, do you think they'll get the hint?

Haha, you'd think the tour guide would ring a bell or yell a warning before entering any living areas of the ship.

Good stuff!! engineering components are always de-rated for expected lifespan... whether it be electrical, chemical, thermal, or mechanical stress. Especially in military or space applications, the idea is to reduce stress levels on the component by using them at well below their stated operating load so they last longer. This just shows that India's engineers did a great job with the engineering to ensure components were functional with longevity in mind, in probably the harshest environment possible.
