I run backups on my computer before installing new software/fiddling with important settings/etc. because I've fucked up before.
I'll run backups of phones (or at least verify that they are present) before trying to fix issues on them after nuking my mom's phone which resulted in her losing pictures of my niece and nephew. (Luckily she had sent a lot of those pictures to us via e-mail, but still).
We learn and adjust.
If the pilot can forgive someone for a mistake that almost cost lives, I'm sure any good interviewer can forgive him for a mistake that cost data and will probably never be repeated.

The Captain basically got up before the NTSB and when asked what happened, he responded "I F__ked Up!" instead of trying to deflect blame onto an unforeseen system glitch or other excuse. Its since been known as the "Asoh Defense"

> According to the preliminary report, several decisions of the flight crew were incompatible with aviation regulations and rendered the flight unsafe. Insufficient flight planning (disregarding necessary fuel stops) and not declaring an emergency when the fuel neared exhaustion caused the crash.
By an order of magnitude it sounds like from your comment. Even if you get 99.99% reliability (good luck with humans involved) think of the number of flight movements per day multiplied by the number of tasks that must be completed.
This is why there are redundant checks and checklists and systems in place. To catch human errors, as absolutely everyone in the business will eventually make a trivial yet critical mistake.
Demanding individual human perfection is great, but you'll find you will end up with no workforce.
