737 and MD11 might have some faults, you can't compare the amount of hours flown by concordes with other aircrafts. Concorde had a tire incidents rate 300.000 times higher than on A330. Not only the tire incidents couldn't be reduced to a reasonable level, but the main issue with the fuel tanks being regularly perforated was not mitigated. This has little to do with one specific operator or one specific country...
OH COME ON SFLY, we can all Google statistics, this does not make you knowledgable. There is an old adage that the further you are away from a problem, the simpler it seems; you must be a million miles away. Certain other aircraft were allowed to continue with known stab trim, freight door and other problems, and MANY lives were lost as a result. But this is not at issue here (I'm not stooping to your level and bash Boeing/MD etc); Up until the Paris disaster Concorde never hurt a soul (actually helped save many lives with regular donated organ flights across the Atlantic). This is the stuff that a person jealous of, or not good enough for Concorde might say. I saw with my own eyes the majority of British incidents, did you? No matter what Google tells you, the material and systems damage was relatively minor
