Do you think military planes or even personal carriers are always at 100%? 90%? 80%? How long do you think it takes to overhaul an one of their engines? It looks like the F-22 had something around 50% mission ready.[1] Not to mention a Hurricane messed their training place up pretty bad (as well as my beach house). A classmate in college was in the Airforce and it took something like 10 hours to software upgrade an F-22 and it was likely to fail the first time. https://nationalinterest.org/blog/buzz/air-forces-f-22-raptors-wont-meet-pentagons-80-percent-readiness-goal-67352 https://nationalinterest.org/blog/buzz/air-forces-f-22-rapto...

The F-22 has comical maintenance requirements (they designed for peak performance). Lower maintenance cost was a program goal for the F-35 (within the scope of an advanced fighter anyway).

  If you look at the requirements set by the Whitehouse in 2019 it said the goal was 80% for F-22, F-35, F-15, and F-16. I presume the F-35, along with the others, was able to meet it.

    It's about the Engine, which is 'normally' the most robust and dependable system in a aircraft.

Just remembered a supercar maker also has a retry mechanism in their assembly line for flashing their roms. Shouldnt occupants of such vehicles be afraid of the fickle computers?

  The main difference between the supercar makers and Toyota is that Toyota has enough scale to justify automating the retries and implement an inventory system that lets them flash the ECUs before they get to the line and then pair the right ECU up with the right car. Bigger automakers don't magically have smarter engineers or access to magical materials and chips (despite what internet comments may lead you to believe). They just have to do some things differently because of the scale they operate at.
