Rotornut:
To use a poker-expression: Quantas is pot committed.
And their Q400 might actually work fine, lets not rule that out.
When they work properly, its a very nice aircraft. Indeed.
Regarding the source of the O-ring:
I'm very convinced, that the Danish HCL (the "NTSB") is very interested in finding out, where that O-ring came from, and I'm sure they will actually print their findings in the FINAL report.
So to all the wICEguys: put a sock in it, and read the FINAL report. Prrretty please.
