Excuse me guys but having previously lived/worked in Luxembourg, for an airline, and unless things have changed, Luxembourg sub-contract out their Flight Operations Inspectorate to 'Bureau Veritas' of the French CAA.
So any suggestions that Luxembourg are trying to pee off the French, not oversee things correctly, blah blah blah are bullsh1t.
That said, take a French CAA 'Bureau Veritas' inspector out for a bucket of red wine of a lunchtime then you're sure to pass a Flight Ops Inspection!
