I doubt if the engine failures had anything to do with the subject matter.
My understanding (given without prejudice) from chats I've had with engineers, is that toxic fume events are more likely to the product of oil seal design on the C5 engines, and the fact that damaged seals are not replaceable by our own engineers.
Someone earlier said that we have 5 spare engines... I'm not sure that's true anymore either. I heard that there were no replacement engines now, and that it can take up to 300 days to get an engine back from being overhauled!
Regarding the question of pilots using more than one pseudonym; I suppose there is always a danger of that happening BUT given the fact there are about 140 pilots in DHL, I would have expected a flood of rebuttals if any unfair criticism has been levied!
Finally, we should not knock each other for holding opposing opinions, it is up to the reader to assess the weight of any argument given.
