Five dead at this point, and pretty clear it was an accident.
I gather from the news that one reason there weren't more killed seems to have been that the workers in the Pirelli building were pretty well geared for evacuating, since they'd realized it was a potential target.
We live near Stansted Airport. I can't see a jumbo fly overhead without seeing the planes of September 11th again. Waiting for the other shoe to drop. Maybe it never will. But from now on, that's something we all have to live with, permanently.
The strange thing was seeing the news flashing from puctures of the Pirelli building looking like the Towers before they collapsed, and straight on to Jenin, looking for all the world like Ground Zero after the Towers collapsed.
