Yes I must say I agree,
This certainly is a sombre moment.
However, to quote the Mayor of London:
Us Londoners, indeed the English people as a whole, are a resilient bunch, we will get through this!.
I have to also say, that the London Emergency Services, performed without failure whatsoever and to a certain degree, they need to take a great tip of thier collective hats, as to their speed and their professionalism, in preventing this incident from becoming worse than what it did, in the aftermath.
An incident like this is every Emergency services worst nightmare, but it just goes to show how prior training can lessen the suffering of those directly involved.
