How can we work with imperfection?
The reality, I suggest, is that life is imperfect and we have to manage that regardless of the specifics of the day. Doesn't matter whether the topic be aeroplanes, cars, the state of one's health, wealth, or the attractive lass at the other end of the office, etc ..
Mitigation against the potentially adverse sequelae of such a reality involves a healthy and conservative mix of resources, knowledge, training, and practice, with a fortuitous portion of Lady Luck's smile.
