Sorry M2Dude, but although I agree that the reasons for the premature withdrawal from service lay south of La Manche, the AF incident we're talking about was not due to "forgetting to select the LP cock to shutoff" in your quote
<<What was required in the case of this failure was a precautionary engine shut-down, closing off the fuel supply to the engine totally, and a descent/deceleration to subsonic speed, carefully monitoring fuel consumption all the time. Unfortunately the crew 'forgot' to shut down the fuel LP valve>>
At that time the Precautionary Engine Shutdown C/L did not call for the LP cock to be selected to shutoff (that stable door was subsequently closed). So no procedural errors there.

You could argue that the severe vibration which kicked off the incident should have called for the Engine Fire / Severe Damage C/L in which case the Cleanup C/L would have seen the LP Cock closed - but when? And was this the drill called? IF the Precautionary Shutdown drill was used then it is not surprising that the LP cock was not closed. That's all.

Easy when looked at through a retrospectoscope....

And for what it's worth I think AM and CF were a pair of [edited to say: "allegedly not supportive of the Concorde operation"] who should not have been allowed any authority at all over this precious project....
