I sometimes wonder how so many things can go wrong at the same time. There seems to be something more happening than just mere chance. I mean, you can have a lot of different things go wrong, but why do they all have to happen at the same time?
If you know anything about airplanes, you know that they usually have redundant systems as backups to take over in case a primary system fails. Some of them are so engineered to prevent cataclysmic events that they have backups for their backups. Many newer planes have fly-by-wire systems where nothing is directly manipulated from the pilot controls but are controlled by electronics. Then there might be another redundant system in case that one fails. Older planes just had hydraulics that controlled most things. Although old-fashioned, these did have their advantages. The pilot may have had more “feel” when flying the plane. They felt more connected to it. Maintenance might have been more labor intensive, but you had a good idea of what needs replacing and when to replace it. Electronics, on the other hand, can be a little bit of a different story. Who knows when they’re going to go bad? I have to admit, fly-by-wire makes me a bit nervous. You could lose power mid-flight, and then what would you do? Well, some of these systems actually have limited mechanical backups. This gives them some control of the plane in the event of power loss. It’s just not a whole lot of comfort to me.
On rare occasions, those things that are meant to take over for the failure of primary systems fail as well. This can be the case where multiple points of failure provide the opportunity for an incident. The thing that gives engineers and pilots such confidence in taking that plane into the air is knowing that they have anticipated failures in the design. However, you still want to ask the question, “But what happens when they all fail?” This can leave the engineers scratching their heads.

See, there are limits to our ability to anticipate these things. One summer, during my college years, I happened to lose two jobs within two weeks of one another. I couldn’t have anticipated that ever happening, nor would I. I felt I was pretty safe, moneywise. Having two jobs gave me confidence in case I lost either one. But then, after I lost both jobs I was left with nothing. Even then, I thought, “Well, I’ll just go get another job.” As it turns out, that job turned out to be the worst job I’ve ever had. So, I ended up quitting that one and moving back home.
Whatever downturns we plan for, there’s a limit to how much we can do. Sometimes multiple points of failure all fail at once. It’s not something that you want to happen, but it can happen. If we’re going to depend only on planning redundancies into everything in our lives, we better plan out into infinity…..because, sometimes, everything can go bad all at once.
