>Planes prepare for basically 0 chance of failure.

NO, the entire point of plane safety is that you are prepared for the VAST MAJORITY OF FAILURES, through extensive planning, testing, regulations that force certain choices, redundancy, backups, etc.

Maybe companies should stop trying to play check kiting as SOP for business operation, and be willing to admit that they sucked at business, burned a billion dollars, and didn't even keep any of it to help any of the people who did the work survive for the next few months as they adjust.

You misunderstood my meaning. Planes prepare for, I guess what I'd call individual component type failures, so the flight as a whole doesn't fail. They do not accept a 1% chance of failure. The plane stays grounded and doesn't leave the gate.

Startups on the other hand, (normally) must accept some risk of failure in order to have any chance of success.

Using all capitalized characters doesn't make your argument any better, bud.
