And now for something entirely different
It seems to me that the essence of the problem is speedy suppression of fire emanating from ruptured tanks. No fire - no problem with evacuation.
So, when building runways why not have a couple of well-indicated pads spaced out at each end under which are truly massive supression foam generators which can be triggered from the tower as to half a pad or a full pad of upwardly directed foam spray. They are always part of the runway, just a different colour
Aircraft in trouble aims for pads: commander calls tower for jets: fire suppressed: measured evac: possible hull saved: pads paid for many times over.
Or is it too simple an idea, like cheap external cameras that someone has to be paid millions to come up with!
