Working in the aerospace industry for a number of years, I've seen and created all types of crazy spreadsheets to design aircraft and ensure they are safe to fly.

The good thing about the engineering industry though is that all those spreadsheets get checked by someone more senior than you.

The problem is though, thanks to the increased usage of finite element analysis and more detailed models, the amount of data being pushed around in spreadsheets has grown exponentially.

Far beyond the ability of someone to reasonably check it all.
