M2dude, how is hydraulic fluid contamination relevant to the Gonesse accident?
We understand that you want to make a point on the bad AF maintenance, but I don't think this is relevant to anything else than the tire failure. The consequences of such failure aren't related to the maintenance, but to a particular and known weakness.
All parties involved in the concorde operations were aware of the high rate of tire incidents and associated fuel tank perforations (without counting the BA fuel tank perforation caused by the 10 lost wheel nuts... maintenance issues?).
Pretending that BA wasn't exposed to any risk isn't fairly honest. There was a well known history of incidents with fuel tanks and engine damages with catastrophic potential due to the aircraft design. Talking about AF poor maintenance isn't gonna demonstrate that BA wasn't exposed to any risks.
