Appreciate the patient reply. Let me try a different course, I seem to be having difficulty with language.
You suggest the Trent is being singled out for testing because it was fitted to the accident a/c. Also that Boeing will follow up by testing the 777' complete system by way of mockup, to eliminate (or implicate) the airframe.
I do see your point that the Trent is not being impugned to now. What is alarming to me, (taking as fact your statements re: FP/Fuel), is that there is a new horizon of unexplored chemistry re: FUEL. This is disconcerting, since I fly alot and frequently on ETOPS cert. a/c. That Boeing hasn't finished their mockup, and other engines are not being tested, my assumption is that either the Trent or the Fuel is drawing most suspicion, or the several investigative bodies are being rather careless with conclusions needed on a more timely basis.
Are Chemists that expensive? Forensic Metallurgists? I'll help pay. As will all who fly.
