But, The concorde crash was caused by something outside the control of the

That is a totally unrealistic line of thought. There will be FOD on
the ramp or runway as some point in an airplane's operating life.
Had that small piece of metal not been on the runway the day that
the Concorde crashed, it would have been on some other runway some
other day. An airplane that is designed to crash, burn, and kill
over 100 people when it its a small piece of FOD is an aircraft that
is both flawed and an accident waiting to happen. The only curious
thing is why it took so long. In fact, a previous time that a
Concorde hit debris and punctured the fuel tanks, the aircraft managed
to survive without crashing. That is probably the true wonderment.

SMALL piece of FOD? Or a big chunk? Whatever, it shouldn't have been
there.

It shouldn't have been there in the sense that even in the real world
airplanes aren't supposed to shed small pieces of themselves, or in the
sense that this is just a bad thing? In the first case, the idea that
a piece of metal might have been on the ground was not only wrong, but
unforseeable. I've yet to hear anybody say that this is the case, and
that there's no realistic way that such bits of metal would find their
way onto a runway - therefore, regardless of the misconduct (if it was
misconduct) of the flight that left the offending piece of scrap, the
possibility of such scrap would appear in a spot that would threaten
Concorde was forseeable and should have been a design consideration.
