Perhaps in the future, this will serve as a learning experience and churches can modify their design to integrate fire prevention methods. It is generally agreed that churches are a tough structure to protect when there is fire.
One thing that #NotreDame has in its favor - @PompiersParis are world class firefighters.
I saw their work when I served on a board for the @IAFC & they have as strong, dedicated and skilled responders as you'd find anywhere in the world.
And my thoughts are w/ them all today.
