Most staggering example was trying to get a very very small box of engine controller CPUs from Penang Malaysia to an auto plant outside of Philadelphia to get there before 8am shift start. Only way to make it work was hand carry from Penang through Singapore to Anchorage, clear customs and then rented Learjet to Philly.
Penalties for late delivery were massive. In this case had we been a couple hours later would have resulted in cascading loss of production resulting in auto union people needing to work during their summer shutdown and quite large cost.
Semiconductors are different from other parts. They take a long time to manufacture. And, sometimes you think you've made them but they just die for whatever reason. If you want to make a new factory it takes years too. I wonder if the auto companies have learned to keep some semiconductors around just in case. Oh wait. No.
