flapping madly
The die is cast. The problem is well framed, in Regulatory action and in events of nature. The bottom line in revenue flight is to make money, and not kill too many people in its pursuit.
If, as Bolty implies, the entire TRENT issue folder is down to gremlins who cannot read a digital torque, then fair enough. Likewise if it is hungover bench monkeys with double vision who "counterbore" evil into the din.
We will see as events move along. Either the TRENT 900 can produce its touted power without shaking itself into bankruptcy, or it will fail. When 200 cycles loom nye, it will out what the Group has concocted so far as safety/profit.
It remains to be seen who values which side of the equation more.
