I understand they are planning to build a steel net in both ends of the runway in Congonhas. Also soft cement as a escape.
If you have one of these, I can't quite fathom what the point would be of having the other.
The "net" really intrigues me, however, and I'd like to know more about this scheme, if it's anything more than someone's blue skies idea. Active? Passive? It seems like it could cause as many problems as it might solve.
Does anybody really think having a net at the end of 35L would have changed much? I believe it might have saved some folks on the ground, but maybe not even that. IIRC, the TAM flight exited the runway to the left prior to the threshhold.
