FWIW.
Fuel Chemistry was never "mysterious", "Heretofore well understood", or lacking for standards.
It was a Straw man, such that RR could redesign a duff Fuel/Oil Heat Exchanger, and re-enter the playing field as though the design was not dangerous.
Qantas32? Same-O. An AD was relaxed, and an engine exploded in passenger carrying flight.
Comet and Skin? 737 Skin? Rudder? Pilots who hear the STALL WARN and PULL?
Any one see a pattern? No, Engineering is not a "compromise".
Spec. Duty cycle, Training, etc. These are compromises. There is no excuse for a Pitot Tube gnarling up at altitude.
IF that is what happened. Most people never learn, and most of those capable of learning are too easily distracted.
