I see aviation sentiment raised from time to time. In aviation failure is catastrophic, and systems you operate do not change on the fly (pun intended).

You can probably drill SREs that way but you are only teaching them how to _react_ efficiently, not how to _fix_ unique unicorn root causes of these failures. Aviation analogy would be an airplane engineer that tries to drill himself for in-flight engine failures AND engine debugging / engine redesign both at the same time.

It never made sense in software engineering, and never will. Minute spent on drills is a minute better spent on reworking codebase to reduce changes of future incidents. This post is very SRE centric.
