Actually there have been many deaths on the 737. Here is a list of them. If you count crashes the death count is in the hundreds. Many of the crashes/deaths were due to bombs or hijackings or weather or pilot over/undershooting the runway but there are a number of them due to something wrong with plane parts or they couldn't figure out what caused the crash. https://en.wikipedia.org/wiki/List_of_accidents_and_incidents_involving_the_Boeing_737 I'm opposite of you, I prefer Boeing over airbus. Part of the problem is that airbus is fly by computer, there have been problems because a mechanic blocked a vent or sensor or there was a failure in one of them. And no, I'm not in favor of driverless cars, even though I worked with computers all my life I still don't think the computer can react in every situation like a human does. It is only as good as the programmer programmed it. This is JMHO. As for fatigue on planes, the remedy would be to replace those parts. The Aloha 243 problem was because there were cracks in between the rivet holes, eventually the small cracks became one big crack and with the plane pressurized it eventually ripped the top fuselage completely off. They needed to have replaced parts of the fuselage to prevent the accident. Now there is a lot more detailed examination of the plane, they have equipment to detect micro fractures in the fuselage and parts to prevent metal fatigue. I guess more examination needs to be made for engines and their parts.
