I am only disagreeing on one point. A big part of the hawiian air 737 convertible incident was a lot pencil whipped inspections on those aircraft. The employees started pointing fingers to save themselves. The cracks in the fuselage would normally have been found waaay before failure. A lot of folks lost their jobs because of that. A buddy of mine, His dad was a pilot for em at the time. The feds came in, inspected the fleet, marked almost all of em to be cut up for scrap.
