Well since when are people that stick to the facts considered narrowminded?
Do you really have to believe in weird conspiracy theories, whitewash operations and cover up stories to be labelled openminded?
Let's face it:
if the Continental Airlines debris would not have been on that rwy, there wouldn't have been a Concorde crash eighter, no matter how many contributing factors (tailwind, overweight, CG at the edge, ...) you consider.
However, if you take away all your contributing facts (by using a perfect plane with a perfect crew in ideal situations) but leave the piece of metal on the tarmac, can you guarantee me the rupture of a tyre would not have lead to an accident as it did now?
