Lately I've been flying a lot and even now, after hundreds of flights, each time the plane takes off I think about how amazing it is that this whole air-travel system works so reliably and safely. Kudos to Boeing and Airbus engineers.
I've worked in nuclear energy, surgical medical imaging devices, and in the auto industry - and it really gets me in a tizzy when a fresh "agile MBA manager" expects a "quick hack" solution to some of these problems. There just isn't always one when quality/reliability are requirements, not nice-to-haves.
