Trope A Day-Disaster Dominoes

Disaster Dominoes-Spacecraft are very vulnerable to things going wrong and having them go wrong very quickly. To prevent this, maintenance and repairs and keeping up your hardware is vital. To ponies that haven’t ever been in space, spacer pony obsessions with cleanliness, maintenance, and working the schedule on making sure things as trivial as flashlight batteries are good seems weird.

The ponies that survive this lack of obsessive care about checking things when disaster happens usually either never go into space again or they start being just as obsessive.
