But to compare the Vulcan operation to that report and the Thunder City operation seems to be miles apart in real life, especially as the Vulcan still has full manufacturers support.
That's the spirit, Nut Loose. I'm sure that the delegates from the South African Aviaition Authority would agree, along with Shell, and the other high profile sponsors who trusted Thunder City to operate in accordance with the stated and accepted proceedures.
As it goes, apparently, the were concerned with the corrosion in the HP and LP compressor casings as opposed to the turbines, and therefore, I'm as surprised as you are as to their chosen path to deal with that. They are also down to a supply of NO further certified engines now, there are no spares.
Perhaps in light of this, as harsh as it may seem, it might be a good time to look over the proceedures and practices of all former military aircraft operators.
