I believe the guards were added after the fact.

Have the Concorde less fuel in its tank it might have survived but regardless we are talking about stupid engineers who think they know better than the laws of physics. and cheap aircraft companies who continued to run unsafe planes despite numerous serious design flaws. The Concord was fine, I believe that all culpability rests on Continental airlines and McDonnell Douglas and the engineer who installed the aftermarket part incorrectly.
