Maybe the industry has for too long "dumbed down" the public on what is normal, what is routine and what is scary. I know when you talk to fearful fliers one-on-one its relatively easy to explain that you have lots of redundancy and that a precautionary return to a nearby big engineering base is simply that....a sensible precaution.
Years back I had a chance to see the daily rap sheet of faults, flaws, mistakes, diversions, go-arounds, air and ground returns etc for a very big US carrier with 500 ish aircraft. Make your eyes water if you knew no better but actually as most here know, was relatively routine.
