These attacks have made me think about the secondary effects of the Underground explosions. I have read several articles on how services were disconnected and rerouted after the Trade Center collapses.
In this case it would be extremely important to restore power and lighting to assist in the rescue effort. I am not familiar with subway systems but I would think that they have backup systems for emergency lighting and ventilation.
The evacuations were well coordinated and done quickly. That is an excellent example of the British response system. What would be interesting is to see how they deal with multiple problems in different tubes. I would think that ventilation would be a priority after the risk of fire had been assessed. Is this something that should be trained for on the scale of todays attacks?
Unfortunately I think these lessons will be put to use again.
Our thoughts are with you.
