I DON'T support or reject the decision itself...
I accept that as a reasonable response and I respect you for it. I have read countless of Accident Reports and scenarios which have lead to disaster, where cause and effect have been intrinsically linked (swiss cheese model using your vernacular). Now I am no aviation specialist and I do not possess a crystal ball, but time and time again, past incidents receiving the benefit of PPRuNe inquisition alongside the transcription from CVR's/FDR's have shown pilots trapped by outcomes determined by fate.
Whilst the T7 is ETOPs compliant and thus able to fly 3.5hrs on a single engine, if resulting damage had subsequently progressed a single engine shutdown (damaged fan blade, increasing engine vibration, etc) and there was deteriorating weather condition at all reasonable alternates, attempting to balance asymmetry with strong windshear (swiss cheese), may well have occasioned the matters where a collective wisdom could be applied when the CVR stops recording.
Lets face it, more serviceable aircraft have sadly been caught out without any advisory status warning of less than 100% systems performance.
